I bought a few bits and pieces to try and build my own drone from here http://altigator.com and they seem ok with timely delivery in Europe.
I thought I added Altigator already, oh well. I have used them a few time as they sometimes have things I need that other places don't. Some of the stuff is a little bit expensive, like all the old Mikrokopter stuff - I mean who wants that these days? Still, like I said I have used them a few times and they do deliver quickly, only takes one extra day than ordering something here in the UK.
