I've purchased from both Cointaker and Comet. Cointaker had great customer service, no restocking fee on returns, and they shipped the day after I ordered. Their LEDs were of good quality (I bought both flashers and a random assortment of others) and priced a bit higher than Comet.

I ordered from Comet 5 days ago. It took 4 days to ship my order so that was surprising based on the reviews here. There is a restocking fee for returns but pricing is very competitive. I can't vouch for the quality of the LEDs yet but I couldn't imagine they'd be inferior to Cointaker's based on what people are saying here.

Have any of you purchased the LED OCD kit that makes the LEDs fade like incandescent? Just got mine for TAF. I can't recommend it enough! Easy install, pretty easy config.....IMHO a must for anyone moving to LEDs.
