We have had great service out of our Outwell tent. We have a Montana 6 for the whole family, a bit big for a weekend pit tent probably, although you won't be short of space! It has stood up to some severe weather and kept us dry. Take a look at Birdland 3 or Birdland 4. Separate sleeping and lounge/pit space and standing room throughout and good sized windows so you can see to pit if it is raining and you have to zip everything up.
Often some bargain used ones on eBay if you are prepared to collect:

This is a good resource to get real user reviews of a lot of different tents:
