Our 9-man Tentipi Varrie (now called Safir I think) has been superb.
I bought a titanium stove from the US when exchange rates (and ti prices) were favourable. We managed 6 people and the stove for a mountain bike weekend in Mabie and it worked out great.
My brother has the 7-man Arran (probably renamed, but the cheapest polycotton Tentipi) and that’s superb too. Still big enough to put the stove in, but only with 2 people really.
A friend has the Belltent and their cheap stove and it all works fine too.
Bell tents are roomier because of the vertical walls, but take longer to pitch and aren’t as suitable for backcountry as the Tentipis.
Here’s some pics of ours:

A bit like Islabikes, Tentipis are really expensive but seem to hold their value extremely well.
