One of the pistons on my driver's side front caliper was sticking. Lexus replaced it under extended warranty. Unless you track your car, I recommend OEM.

Aftermarket = expensive
Swapping calipers from other cars (supra or LS) = costly + custom work + time

your best bet is get OEM from local junkyard
option 2 - get a used one from classifieds section if you dont mind paying shipping on a heavy 30Lb piece of metal
option 3 - bring your current one to lexus to be rebuilt... $$$
option 4 - aftermarket or caliper swap

No problem, and yes, you will need to bleed the brakes.

I believe my pass front caliperis sticking as well
. Changed the pads but don't recall using any grease on the pins ... so could this be the problem or more likely its the caliper itself (piston verses bolts/slide pins)

I'd just take it back apart and look at the slidey pins. I worked on a GS the other day, same brakes as the IS and the lower slidey pin took a slip hammer to get loose. Water got in behind the boot and it rusted up.

Three options for stick brakes:

1: slide pins not sliding: (usually shows as severe uneven pad wear inside vs outside pad) solution - remove, clean and lubricate; remove replace and lubricate; or if it is frozen badly, replace the caliper mounting bracket

2: sticky caliper pistons: (cant compress pistons, even with bleeder open) solution - replace or rebuild

3: bad brake line (allows fluid to compress brakes but not release, diagnose by trying to compress caliper pistons and if they won't compress at all to start but if you open bleeder, they do compress, brake line is bad): solution - replace brake line
