I just bought 20 M of WS2801 strips, 5 volt version,black pcb,with the silicone tube jacket, from ScottLED in Shenzen. That's (4) 5 M rolls. They all work perfectly. i didn't get it with the epoxy inside because it would be hard to cut and splice back together. Important note: the 5v versions are all the lower speed type. 12v is the high speed. Mine are updating at approx 44,000 + individual LEDs per second.http://scottled.en.alibaba.com/product/725919541-214500503/led_strip_WS2801.html
I took a chance and didn't order through Alibaba, but I did use PayPal.
I emailed Scott Liu and he sent me an invoice that I paid with send money
Took about a week and a half to arrive.
I have one of the T1000-B controllers with SD card coming(from ScottLED) for use with some of them.
The others are getting my own custom scrolling text program.
My price was $ 158.00 'ish including FEDEX. FOR 2 M.
Basically $16 / M.
I ordered 10 M. Scott accidently double shipped and I did the honorable thing and paid the Man for the
the 2nd set of 10M and I ordered the SD controller too.
I'm very happy with this outfit.
