I really like the Taco Frijole on the Taco website but for $375 I am thinking there has to be something better for the price. Any suggestions on where to look?
Since you like the small frames, (and a lot of us do) why not check out some of the re-pops. Several members here can bend up and weld a frame and might be interested in helping you out with one. Otherwise, keep your eyes open, and be prepared to pay. A beat up Flexo roller requiring significant work will run you $500. An original Frijole, a little less, if you can find them. Do a "wanted" ad.
In the meantime, I was looking for a small frame project for a two stroke motor I've had laying around. I found this off of ebay. A re-pop, not that good on the welds, but a good job of frame alignment, and since it is not an original anything, I can pretty much have my way with it!
This will be my next project. The ebay seller is a guy in CA who sells a LOT of seats. Roller was about $250 shipped.
