A lot of guys use the Mystery Ranch Pop Up series. I have a 28 and love it although I haven't packed a deer out yet, it's very possible, been done by many, and on my list for this year. If you're patient and look hard enough they can be found used for $200, or new on sale for $220 and up. Seems steep and I said the same, but that's nothing compared to some of the others. The ones that Cline mentioned are great, but they are even more expensive($100-$400 more) but I believe they could indeed make pack outs even easier.
It's all relative, a lot of guys buy a new bow every year, don't do that for 2 years and you can get a really nice pack.
