This one works well. Keep an eye on the R-Value for indicating warmth. Cheaper than the Thermarest NeoAir XTherm (which apparently is good enough for snow camping with an R-Value of 5.7), this one is an R-Value of 3.

You just missed out on REI's 20% off sale, and Backcountry typically offers a similar 20% sale at the same time to compete (i imagine). But if you have an REI, they encourage you to lay out sleeping pads (and bags) to test on the floor. But as someone else noted, it's nicer to go when there's low traffic, so you don't get stepped on while testing.
