If you're happy with a 375 H&H, or 416 Rem Mag, I would buy a new Model 70 for just over $1000. The CZ 550s including the more expensive Safari Classics tend to require some work. If you want one in 416 Rigby or 458 Lott, then I'd recommend a basic CZ 550 in those calibers, they are great deals and plan to spend a little money on gunsmithing (smoothing the action, etc, though your rifle might not need it). I have a "basic CZ 550 plus some options that was originally a 375 H&H and is now a 500 Jeffery. I have a little over $2000 in it and it's a great gun, but it's been to two gunsmiths to get it right (500 Jeffery's are notorious for feeding problems).
