One thing I am sure of, if you are building one now and may want to recover some costs (sell) at a later date only use the best quality parts/stock/smith you can. Anything less can be perfectly serviceable but will bring pennies on the dollar.
That being said, I think there can be some great bargains on a rifle already done.
Not that many north of the border that come up, but I keep my eyes open, just in case!
