You probably won't find a lower price than that for a rifle/scope combo. The scopes that come with those combo packages aren't usually very good.

.270 and .30-06 are extremely popular cartridges for deer, and are versatile enough to tackle most other game animals in North America. Other cartridges you might want to consider for the chores you have described: .243, .25-06, .257 Roberts, 7mm-08, .308. You don't say whether you've got much experience with firearms. So, I don't know whether recoil may be an issue for you. To me, a .243 is a lot more fun to shoot, particularly in practice sessions at the range, than a .30-06.
