I use a Black Wolf Gobi 2 man tent. Purchase price was $110. It packs reasonable small and takes up about half the room in one pannier, is easy to erect, and has plenty of room inside. I originally used a small one man tent, but ti was just too squeezy once some gear went inside as well. The Gobi has lots of room for a full size air mattress, and room to spare for my stuff, as well as having enough headroom to be able to kneel up. The photo of the tent beside my bike at Blackheath has a fuzzy patch, as there was some crap on the lens that I didn't find until after the rally.
