It's a really fun thing to do and there's an incredibly wide variety of things to choose from. I tend not to go for the themed stuff like Star Wars stuff but there's some cool themed sets for sure. I do mainly vehicles and build Lego Technic with complex gear boxes, pnumatic movement and motors, some are remote controlled.
Its a shame Lego isn't available, a little weird also.
Thanks for your comments, I hope you manage to get hold of some Lego someday.
