In reply to heidi123:
We use them for d of e and they are small, have a tendency to sag in the middle, have no real porch space and water can get in when you fully open the door.
Having said that they can be found very cheap and are pretty waterproof.
Depends what you want it for, if its 1 night trips camping in valleys its probably fine. If multiday backpacking or camping high up i dont think it is a good option as it would be a squash and unstable in high winds.
You can get some excellent priced second hand tents such as the voyager on ebay and thats what i would do.
If you get a banshee i think you would find it restrictive and soon want to buy a different model.
