I think if we went with an enlarger lens, we could forgo the F-theta lens. Enlarger lenses are also a flat-field focus, it's simply that it would require software correction - the angle in vs. the angle out is not based on F*theta, it's based on F*tan(theta). Enlarger lenses are anywhere from free to $300-ish, instead of $750-$10k.
See here for more optics info on lenses, and lasers in general.
The Form-1 (from kickstarter fame) uses an X-Y galvo scanner, though the reason I'm thinking of going with a delta bot for proof-of-concept is also so I can get a larger build area (12"x12"x12" is what I'm planning).
