If it were I... I'd only buy a #3 for a future project. If one has to pay the price for a #1, one might just as well buy a #1.

+1 on GH advice.
I would only do a #3 for a project if it were really cheap. If I was planning to restock it al la #1, unless looking for really custom wood, why not buy a #1 and rebarrel?
Having said that I have a couple of #3's that I really like. One was purchased with the wood reshaped and accurized, a hornet, very accurate and attractive. The other is a 375 win, and, I know I know, shortened the stock and put a decent pad on it. Makes for a light, quick handling, close woods rifle. Anyway its fun to play with.
