I did the same thing, had a few parts including wheels that needed to go somewhere so another frame was the obvious answer. I admit the rarity and colour got the best of me in this case but now I have one more I can add to what was already more than enough ( 5 bikes ). You know the usual thought: there are worse things one could be doing.

Besides, you might be the only one around with one and that adds a certain amount of pride in ownership, in a good way.
