I am sure that most of us here do not soil our hands with clone brands and would never allow our precious LEGO collections to become contaminated with cheap rubbish made in the far east.
That said, I suspect some of you share my fascination with clone brands, if only to think 'how on earth are they getting away with making such blatant copies of LEGO sets/parts/minifigs/artwork, or whatever.
If so, you'll find a document created by Brickish member Anthony Tomkins entitled Communist LEGO, a review of some Chinese copies an interesting read. Anthony has tracked down and imported a dozen or so different brands and written reviews comparing them to LEGO. Most are absolute rubbish, but it seems there are one or two that are not that bad and better that M??ab???s, which, actually, I guess isn't saying much, is it? :)
