In reply to mrcharly:
Depends on your budget, but one of the various quasar clones out there may be worth a look? Technically a 2-man, but that actually means plenty of space for a solo camper to stretch out, sleep, get as far from own socks as possible, read, drink beer, count hairs in own armpit, ponder the inherent hilarity of the word "udders"* etc.
Have had a week in bad weather in a 1.5-man side entry tent with rather restricted height at the ends - and, at 5ft7, I don't usually have problems with height - and it was horrid, not just in terms of lack of usable space but in terms of getting the thing to stay up while the wind flogged it about and the ground got progressively soggier to the point that the pegs wouldn't stay in.
Have had an original Quasar (and various problems with poles, boo hiss), and when it wore out replaced it with an Alpkit Kangri, which is basically the same thing. Both much better in terms of internal space, behaved themselves in strong winds, and weren't reliant on being able to get the pegs to either go in or stay in to stay up.
