Grey Card - Where?

[memories]

Where can I purchase a good grey card? Went to a seminar this weekend and they had a grey card for $50.00. It was the type with 3 bold stripes, approx 10" square, and made of some sort of cloth, not paper or plastic. I thought $$ was too high. Definately want one with the 3 stripes. Are they hard to find or am I looking in the wrong place.............or am I too cheap?

I remember seeing a thread that recommended checking out the gray card from B & H photo website. Said it also has a white balance card on the back.

I got mine from B&H. $15 for 2 large Kodak 8x10 and one small 4x5 one I keep in my backpack.

EDIT: Oops, I didn't read your whole post. The ones I got from B*H do NOT have the stripes like you wanted.

Why do you want the one with 3 stripes? I use the stock Kodak grey card and dry-mounted their grey-scale and colour control cards to the edges for convenience.

I guess grey card is not the exact term. More like a digital calibration card that will help me get the correct white balance in a picture with strange color casts. Should be easier than changing white balance settngs on the camera. I fixed the problem by just shelling out the $$ for the one I saw demonstrated. Just thought I could get one a little cheaper. Ordered at digitalphotosolutions.net/seminaroffers

For custom white balance, you don't need that 3-banded card. CWB relies on your providing the camera a neutral control point; then in subsequent pictures, the camera applies the corrections it needed to use to get that a neutral grey. Or you use it as a target in your own post-processing, again as a known neutral colour. White's not especially good, since you have to decide whether it's really white and not blown out. As I understand it, the striped card provides you with 3 spikes for checking your exposure on the histogram, but any advantages in white balancing are going to be marginal at best. A grey card will work better with a hand-held meter too.
