There are lots of similar bags. They may be a good choice if the budget is super tight. I used a Slumberjack Superguide on my first tour (Trans America) and it was OK.

That said, a good sleeping bag is an item where you get a lot of improvement in lighter weight, smaller packed size, and improved comfort by splurging a little. The sleeping bag and pad are the first items I'd look at if willing to spend a bit more and upgrade to a nicer model. Marmot or Mountain Hardwear make down bags that are a joy to own and use IMO. They also outlast synthetic bags which tend to compress and lose loft over time. Oh and I highly recommend the NeoAir Xlite pad, light, comfy, and packs super small.
