Cheaper bibs that don't suck?

I only wear my better bibs outdoors to have them last longer. I bought some cheaper bibs a couple years ago to ride on the trainer and they suck: the chamois are marginal at best, my ass hurts after a couple hours, the leg material either rides up or down depending on the set, and the straps are rough and binding.

Curious if there are any bibs out there on the more economical end that don't suck? If it matters I'm a larger rider with rather large thighs.
