I just ordered 10' of the Black Pica self-stick vinyl (part #49-0474-10) from HappControls for $2.35/foot. The roll is 49" wide and you can order by the foot.
The price is normally $5/foot but it is on sale right now. If you search their site
www.happcontrols.com for "vinyl" you will see the black pica vinyl and other vinyl available. Their site does not mention the sale price, so I was pleasantly surprised when I called to order and found that I would be saving more than half the posted price

.
Also, I have no idea whether other vinyl selections are on sale or not, but for $2.35/foot I got some of the Black Pica vinyl.
Hope this helps people......
