Some of the brands I've used and really liked were Big Agnes,Eureka,Mountain Hardwear,and REI's store brand. My Big Agnes is the smallest,lightest, and cost the most. It's a 1 person and I think ran me about $300ish. But I was going for really light weight & small size.
For what it sounds like you'll be doing I would check out the REI brand. They offer good quaility at a pretty reasonable price. If you really want to save money,check out the Coleman's.
