I have used them in the past. Good turn-a-round time and super nice folks. I have not used them in about a years time since I have somewhat graduated from building pre-compiled kits to doing all the sourcing myself etc.
To that end, I never had an issue with them and the parts were good quality. In fact, it was MKLEC that actually introduced me to low profile caps.
hope that helps
Yeah, 220, 221. Whatever it takes.
