The issue was not the availability of the frame, but of parts for it. A lot of stores (locally anyways) don't carry a whole bunch for 1" threadless, if at all. So say your headset goes bust, and you need one, you're pretty much SOL as far as getting something from a local store the moment you need it. Granted, chances of needing a headset ASAP are slim to none, but in the chance it happens, it would be irritating at that particular point in time.

At the same time, however, if your local store does have 1" threadless parts (spacers, stems, random little things like this) it's possible they'll let it go for dirt cheap just to get rid of it since it's been sitting for so long.
