I get feeders from RP exclusively.

I can attest to the variation in size differences, as well as the rats being covered in urine alot of times.

I just don't know where else to buy them, I buy em on sale, and get em delivered to a local show so I can save on shipping charges.

I've tried local people and EVERYTHING local comes from one supplier, and they're rats are infested with some sort of lice or bug.

RP works for me for now, but I wouldn't hesitate to buy from another company If i could find consistent good reviews on any single source.
