The two LEGO Factory space sets can now be bought from LEGOshop.com in Europe. However they seem a tad expensive to me. At £70 (or €100 in Germany) for under 1000 pieces they do not compare well with Market Street, for example, which is £10 cheaper and has about 400 more parts. They don't seem to be available from LEGOshop.com in the US, but I suspect they'll be somewhat less than $150, which the exchange rate would suggest given the European prices.
