There aren't too many bikes I'd pay over $1800 for, even though I've exceeded that number on several occasions, either in total build cost or purchase price for a complete bike. At this point I have all of the really expensive bikes I think I want, so it's more a matter of riding, maintaining, modifying and enjoying what I have than always being on the lookout for something new. I don't really care about resale value on them, since it's unlikely any of them will be sold during my lifetime.
But I still have a number of neat-O projects in storage. Admittedly, one (or possibly two)of them approach or exceed that magic $1800 number. So I'll likely take a loss on those when they go on the block.
