I had something like first wheels (Bertini Mio) in the single, and i wanted the first wheels but it wasn't avaliable at all in Australia when we needed a double, but i never had a problem with the front wheels (its like a bugaboo), but that being said, i never test drived it as a double.

Look at Oo (i think?) otherwise PM me, they have free shipping and i think it is $400 all up for the double, which is pretty cheap for a double pram. Doesn't come with basinette, just the 2 seats, but as you can make 1 seat horizontal, from experience you don't need the basinette, iuts just 1 extra bit of baby junk to have around.
