The title of the item and the description/picture don't match up.

title lists WS2801 chip, but the description does not.

Good eyes!

Ray sells a similar string at $0.53, it's the shipping that make a difference. For 200 pixels, Ray would be $126.35 with shipping, while your source would be $105.26, about 17% less.

But the vender is pretty new (less than a year old with only two real feedbacks total!), has shipped their first order of this item only recently with no feedback yet - and the discrepancies above would need to be investigated; you get to find out how well they communicate!

Some of us will be interested in how it turns out if you do order.

I have not yet design PC boards, but I will be doing this soon.

Any chance of more product in the store, Robert? I'm very impressed with your designs, but I'm not taking on etching boards yet (enough new stuff on my plate!).
