I would also suggest looking for a Traditions Yukon in that range. I just got one and it seems to be a solid rifle for around $150. It felt better to me than the Wolf, about the same as the Buckhorn.I got mine off of Gunbroker for far less than that. Haven't shot it yet, but only heard of one person who had trouble finding a good load.

I did see Buckhorns at the local Walmart for $59 after the season last year, so if you can wait...
