I stopped using a cot when I discovered the sleeping pads. They're lighter and (in my opinion) more comfortable. A lot of people are getting away from cots because of their bulk, weight and setup time. You can still get a good one from
cabellas.com but for the same price you can get a
Thermarest pad
If you're camping from your vehicle and really like cots, get one. The one in the link is similar to my old one and is great. If you're backpacking or looking to pack light, get the pad.
