Performance-wise, and from experience, the Weatherby Vanguard is very hard to beat for the money, and I'm hearing the Series II is an improvement over the original.
This IMO is about as good advice as you can get. HB gave you minimum and most popular calibers,if it were me i'd pick one in the middle.
