Cheap ebay calipers? Anyone have experience?

I'm looking to save some time and effort rebuilding the calipers I have by clicking the buy button. Also money, I like cheap. I've found some that are around $110 per pair shipped and look okay from where I'm sitting. I've bought dozens of cheap motorcycle master cylinders and have always been impressed with the quality. I don't think I've purchased cheap calipers though. These are stone simple systems but also kinda stop you. So does anyone have experience with these budget priced units or similar? They look good to me but figured I would ask others.

EBAY LINK to fronts

EBAY LINK to rears

I meant to post this in the GRM forum not the project area. Can this be moved by a mod please and thank you?

I'd expect they're similar quality to cheapos from the FLAPS, so they may work or they may leak or seize up. Maybe just try the rears for a bit before you swap out the fronts.

I bought some cheap ones for a Polaris ATV. No problems so far. Quality seemed decent. I didn't have any issues bolting them up or bleeding them.

I think I'm going to pull the trigger on them and see. Fingers crossed they do brake stuff and not break stuff!

I bought one cheap ebay rear caliper for my Civic and they seem fine, no leaks or issues with the ebrake working. 

Apparently someone else in the local Honda community found out they have rear ITR calipers too (OEM Nissin are really expensive) and he hasn't had issues with them either and have the correct brake bleeder location too so it isn't just an RSX or EP3 caliper. 

I'm no expert, but it seems to me that brake calipers old tech with fairly loose tolerances. I don't see why some factory in China couldn't make a pretty decent caliper and undercut the rates here. The seals aren't exactly expensive either. Am I off base?
