I have four of the Seneca rifles, all in .45, that I have purchased over the past few years. The prices ranged from $175 to $300 and one I pieced together from parts I bought on e-bay. I bought them because they are a neat little rifle and because I wanted practice engraving. I have engraved all the brass on three of them and am working on the fourth. The stock shape around the lock is a little "clunky" so I have also reshaped and refinished the stocks. For the price, I find them well made, sturdy, and fun to shoot So, to answer your question about price, I would think $300 to $400 would not be to much to pay for one in good shape, especially considering the cost of just a lock, a stock blank, and a barrel if you wanted to build a similar rifle.
