Question about sleeping bags for backpacking

[petegz28]

Ok, all you outdoorsy types, I have been looking into some sleeping bags that are good for backpacking. I have seen the down bags that stuff into basically a coffee can, or so it seems. This isn't for extreme use, just for a couple over night hiking trips and what not.

I have seen prices from $100-$500+

Again the most important thing here is that the bags stuff down to small size to fit in the backpack compartment.

Thanks for any ideas or suggestions
