I just looked at The North Face on line catalog and I was surprised and delighted to see that the VE25 was still available. It ain't cheap, but it is a serious four season/expedition tent. With anything like reasonable care, it will serve well for a long time. It has been around since the mid 1980's which says something.

I am not sure I would recommend it for you - it is probably more than you need, but it is a good point of reference. my experience with the VE25 has been very positive.
