I'm trying to find my ideal position on a new Fuji Aloha. In order to do some experimentation on fore-aft positioning, I'm trying to find a seatpost that is reversible, and, that is affordable. To be clear, I'm looking for a post with a ~20mm "setback" that has sufficient angle adjustment to be used setback or reversed so that it places the saddle closer to the bars. I've seen a couple that look excellent (Fizik Cyrano, Thompson Elite), but are in the USD 100+ range. I'm looking for a cheap alloy post to experiment with (Kalloy, Easton EA30/EA50 range), not a Profile Design Carbon Fast Forward for competition. [27.2mm w/ standard rails, in case it matters.]

Thanks.
