In reply to Rudi B:
I had a zhota and did a couple of hundred nights in it and loved it in loads of ways! Its extremely spacious with the unique "spider pole" and its got great pockets and is really easy to pitch.
However, the materials are not very robust particularly on the ground sheet which we wore through, don't even think about buying without a groundsheet protector. Also the seams weren't sealed correctly around the guy rope points on the outer so it leaked from new! Think this was a manufacturing issue Alpkit were aware of but didn't inform customers. They did however send us some seam sealer which never really fully solved the problem, there was always a very small leak in extreme rain. We paid £450 at the time and I felt it was good value but I think they dropped to £250 on sale at one point! At £625 with footprint I think you can probably do better. I doubt you'll get ten years from it, we certainly didn't and we really looked after it!
We also love our Marmot tent it's a Grid 2p! We replaced the zhota with a Terra Nova hyperspace on sale after alot!! of research. The materials are far superior and more inline with those on the Marmot and there are also spares available. The downsides over the Alpkit is that it is quite a bit smaller and slightly harder to pitch, this is mainly due to the stupid mesh pole sleeves. I also broke a pole (my fault) but this never happend on the zhota.
We often talk with fondness about our red Alpkit tent and how we miss it, we even went in the shop it Hathersage the other day to look at it! Having had both however the hyperspace is much more robust and practical and it has grown on us alot, we've used it loads in all sorts of weather and it's like new (except for the pole).
There's one on sale for £675:

The only other tent we were tempted with to replace the Alpkit was a hilleberg saivo but they're £1300.
Hope this helps
