I will offer up what I am doing. I am riding SWOBO liners. They are fairly expensive compared to the liners that are sold at Performance or other online retailers. But the SWOBO liner is very comfortable and very well built. Then I went to my local Kohls and found some cheap poly cargo shorts with minimal seams. It works well for me. The shorts at Kohls are marketed as skate boarding shorts. They have some small tags on them that say Tony Hawk. So, I guess the guy has a clothing line now. I'm not a skateboarder.
If you find a pair of shorts that that you really like, go and buy a few pair of them. This helped me as I was always looking through the laundry for the same pair, even though I had a few pair of shorts. They will last a while if you are switching them off too.
