here's a few comps, not that i agree on the pricing and not that people are always getting what they're asking...

never the less, it seems that very nice restored demons are trading hands in the upper 30's to lower 40's which is about where i'd put a price point on yours. the racy nature of the engine, no creature comforts and deviation from a "stock" restoration are going to be turnoffs to some but the overall tidy appearance and apparent attention to detail will certainly appeal to another set of people.
