Gary,
For the price, it's tough to beat Coleman. On their website, the Coleman Crescent, rated to 15 F, goes for $48.49 and the North Rim, rated to 0 F, goes for 58.99.
I have several Coleman sleeping bags and have one of their exponent backpacking bags that I payed a little more for that has served me well.
I see you live in Round Rock. There's a Coleman outlet at the outlet mall in San Marcos if you'd like to check these bags out "in the flesh", or you could just pick one out and order it online. Of course, you could find some of these at Academy as well.
The following is a link to the sleeping bag section of Coleman's website:
Coleman Sleeping Bags-Coleman™ sleeping bags – adapt to the sleeping needs of the moment.
Hope this helps!
