Cheap but good then look at Vango or Alpkit. I prefer Vango personally. A solid brand from Govan originally (or at least that was how it got its name). My vango tents owned over the years: -
Forec 10 vitesse (two man single skin)
Vango something in two man that was a side entry tent but not a banshee or anything like the ones on sale now. Bombproof and about 2kg. Plus extra, extra long for my 196cm frame!
Vango alpha/beta
Force 10/vango UL 1 man tent
7 man vango family tent
4 man vango family tent
Vango porch awning tarp thingy
Another tent I can not quite remember
I think that is 8 vango / force 10 tents that I can remember. It could be more. I often got very good deals from a small, independent camping shop near Kendal that I think has long closed. I got on well with the owner and he always gave me very competitive prices and/or threw in a freebie. We kept going back, perhaps it was an addiction??
