I've got the Westin step bars... the wife insisted that I have something
for her to step on and these were one of the least expensive.
I've had 'em on for nearly 3 years now and they still look great. The only real problem that I've had is that the pads on the drivers' side both cracked and deteriorated after about 1.5 years. Not sure if it was from me always stomping on them while lowering/raising the top, if it was a bad batch, or if they were just poorly made; replacements were only around $25, though.
FWIW, I bought them on Amazon for $160
