dont know about exact models etc. but i can give you things to watch out for:
1. Go with a cloth cothered wrist support as these offer better comfort over the plastic types, especially over extended use.
2. You can get a normal mouse mat and a seperate purchasable wrist pad, you may have issues with them sliding around a bit but most have a grippy design.
3. If you can try to test the mousemat/pad combo before you buy - decent varies from person to person. What one person likes another may not.
4. If you need something urgently why not use an old mousepad and stick a foam pad to it, cover with piece of cloth and it will act quite well as for what you intend. However, i don't reccomend this for a long term solution
5. good luck, if you find anything post manufacturer and models back on here to let others know!
