Yeah, there's the Tern Verge X11 (with 451 wheels). Much cheaper than the overpriced Dahon at a retail of...oh. Wait. $2699!
Obviously that wouldn't be a
similar Tern since, as you pointed out, the prices are quite
dissimilar. Duh. This is a classic case of erecting a Straw Man only to knock it down. Good job.
Tern or not, the Dahon
is overpriced, as many Dahons now are.
