In reply to peakpaul:
What are you going to do in Ladakh?
If you are going to have your gear carried by ponies, you could get away fine with a much cheaper tent. There are some very strong tents that have oodles of space, but are a lot cheaper because they don't use ultra-light ultra-strong fabrics.
For example, any of the Wild Country range, or you should be able to get a Jack Wolfskin Tundra 3 for under £150 if you shop around. These tents are all good and strong. I have led a trip to Spiti and a trip to Zanskar (both very similar to Ladakh) where we all had Wild Country tents and we were fine. We had a mix of Wild Country Llanos, Q2 and Venturi tents, and they were all great.
If you will be in the tent for a good few days, consider getting a tent rated one person more than is inhabiting it. This will give you a lot more comfort room. A big porch is also handy for sorting through gear, or having tea / playing cards with other folks.
Your tent wear issues in Ladakh are likely to be uv and abrasion. It is high and sunny, of course, and that eats into modern fabrics.
And it is desert or semi-desert, so you need to be aware of the possibility of sandstorms. Also, you are likely to camp on hard and/or stony ground. So your tent will suffer - another reason for buying a cheaper tent.
I would also recommend you get some pegs you can hammer in, and a hammer to bash them in with. I got the Alpkit spikes

Other tips to help you have a comfy trip (for the part where your gear is carried by ponies):
Buy a really thick sleeping mat. As I said, much of the ground is hard and stony, and a three inch thick sleeping mat like

I used a closed cell foam groundsheet protector. This not only protected the groundsheet, it also protected my knees as I wandered round my tent looking for socks or whatever. And it added a bit more warmth. It can get hot during the day, and very cold at night.
I hope you have a great trip.
