I am in an interesting position because I have too many bikes now. I just rehabbed two old frames and i wish i could sell like, three bikes and get one Lynskey to replace them all .... but no one would pay for the bikes I would sell, and I haven't found good homes to which to donate them. Because of each bike's idiosyncrasies I wouldn't want to give them to Goodwill or something.
My wife wouldn't be thrilled if I bought another bike, but so long as I used my own cash that would be the issue. It would be the senseless acquiring of stuff, to which @
Stormsedge refers.
Again, until you know that you really want this bike, you can't get it .... and once you know whether you really want it, you shouldn't have much trouble, I hope.
