2013 was my first year to sequence and first year (of course) to go RGB. Based on what I read on PC & ACL forums, I went with Ray Wu's store. I must have missed the point about contacting Ray directly, so I probably overpaid shipping ("my bad"). I had NO problems with the four WS2811 strips or the P/S I purchased and would not hesitate to purchase from Ray again. I think I received the stuff from Ray in about 2 weeks or so; I was very pleased with that. I had read some posts where it took a LONG time to get some stuff from Ray. That was in the September timeframe, by the way. I also bought some waterproof connectors from DIYLEDexpress. They are very good to do business with and I would not hesitate to do business with them again, either. My 2 cents.
