Kevin,
I have a Chibi seat I'd sell or trade you. The seat has the original seat cover which has some small tears in it. ( a new seat cover is recommended*) The seat foam inside is still "springy" & the metal seat pan (with brackets) is in good condition. I do not know what the difference is between a deluxe Chibi seat & Non-deluxe seat, so I can't say which seat I have... I also have a fairly complete Chibi "rolling" frame with wheels, fenders, and tank ( No engine).
I also would be willing to trade my Chibi seat for Chibi engine/engine parts/ levers/cables/chain.
Let me know.. I can take some pics if you want to see what the seat looks like.

* I am working on getting an eBay seller to soon begin selling good-quality-good fitting seat covers that fit Chibi, BS50 Homer, BS7 Surfrider, Tora, & Taka, since no one currently sells those that I am aware of. I'll keep you posted on how that goes...
