For 2, you can get the Eureka Spitfire 2 for about $130. At 38 sq ft, it's plenty big enough for 2 and weighs about 5 pounds. Very durable, with good peak height and double doors. You do have to do some seam sealing. There are a lot more, usually much more expensive options.

As for cooking, I'm a fan of the MSR Pocket Rocket. Uses gas cannisters. No 'fiddle' factor.
