I love Comet for LEDs and Pinball Life for everything else. All have been great to work with. I've had a few issue with items OOS, but that happens in any business. Typically I'll send a quick email asking when the item will be back in stock and they reply quickly with an answer. This last time they offered to email me when the missing items were back in stock.
PS: I'm waiting on packs of the frosted warm whites.
