This set is great! It has everything: rare minifigures, a car, a helicopter, a tower, and tons of rare and awesome accesories. Now for pros/cons

Pros

• Informatic minifigure(Very hard to find, as he was only in 2 sets, 1 of them being a promo)
• Small Dune Buggy is cool
• Helicopter(rare-ish orange parts)
• Cool accesories
• minifigures are cool
• Tower features cool rock wall and spinning office at the top
• Bungee jumping area at the office

Cons

• Helicopter can sometimes fall off of the landing pad, but if you know how to position it, that doesn't happen
• Nothing else....

So overall, this set is great, especially if you can get it for a good price. The original price is a bit steep but still good, so if you get it for any less, you got a good deal.

I got this set a while back for Christmas. It is really pretty cool. I like the building, the figures, and everything else!

Pros.
Brickster
Pepper
Sky
Informaniac (my sister and I pretend he is Pepper's dad)
2 of Brickster's henchmen
Brickster's car
helicopter
cool pieces like the doors, mailbox, skateboard, bungee cord, computers, etc.

Cons.
stairs collapse all the time
only 1 skateboard
pole that attaches to Pepper's back

Overall, great set, I like it alot.

I got this set for only 25 bucks at legoshop.com.
Boy, what a cheap price for how great this is. My brother, Kieth and I have a large lego town and this is one of the best buildings in it. It is tall, sturdy, and easy to put together and put BACK together. The bottom room has a door ofcourse and a mail box, but also this really awesome, huge computer/keyboard. The helicopter is cool and that infomniac geezer pilots it. The stairs that go up to the helipad are the best. Like in the harrypotter sets, they wind and are hyper-sturdy. Bricksetr and his dimwitted hitmen are included. The tower is held up by the large pole things and have alot of radar mish-mesh on them. The tower is cool because it swings around and it holds an awesome visual-display keyboard. It also has a platform with a "bungee cord" on it so Pepper can leap off and die. It also includes that elusive Sky Lane, ofcourse that old infomniac, and a little buggy for brickster. I give this set a 10 because their is simply nothing wrong with it. Get it on bricklink or legoshop or ebay now!!!

The Extreme Tower from the island extreme stunts theme has a ton of rare parts and cool play-

features. Here are some Pros and Cons

Pros

• A very tall set for just 330 pieces
• 6 minifigures Including the infomaniac and a brickster henchman (different face print)
• Love that you can open the skylight and drop minifigs in usung the winch
• Zipline on the heil to connect to the black hooks around the building
• Some of the Harry Potter "magic" stairs on the side to "grind" on the rail

Cons

• The "magic" stairs can move out of place really easy
• Its takes a long time to wind the rope for the zipline on the helicopter
• Doesn't come with the surfer dude from the other sets.
• this could be just my copy but the computer in the tower under the skylight can get stuck on the wall when opening it up
• The stick used for Pepper's Skating fall off too easily

In conclusion this set has many play features in it build it is a little too expensive for the part count but you can try to find deal on the bricklink and eBay. (i got mine for $17.00)

Come to think of it, this set does seem a bit empty. The vehicles and accessories are great, but the building leaves something to be desired.

Pros:

-Building has nice windows
-Stairs and railing are realistic
-Informaniac's office can rotate and has an advanced computer
-Bungee cord device
-Radar dishes
-Side of the building has built in ladder
-Glass roof opens to allow Pepper in when he bungee jumps
-Main floor has another advanced computer that can open
-There is a safe beside the entrance with a computer chip inside
-Helicopter has winch and a zip line handle
-Landing pad is cool
-Brickster's car looks pretty cool
-Comes with the Informaniac, Pepper, Sky Lane with skateboard, Brickster and 2 henchmen

Cons:

-Stairs don't lead to anywhere
-Building should have more rooms, not just supports that separate the main and topmost floors
-Front lawn is a bit plain

Overall decent set but could be a little better
