I think the Pista looks great in gang green!

but if you're not in a rush, why not keep your eyes peeled for a good price on a bare knuckle. If you're very lucky, you'll find one that fits, is in good shape, and is in a similar pukey green! Building up from the frame will cost more, or take a while if you bargain hunt, but it is a fun and satisfying way to get a bike you'll love.
