I have been trying to find a product that I first saw in filmmaker magazine and am now having trouble finding. It is simply a bag, beanbag type of product you just set your bag on for support. Somebody knows what I'm talking about. What are your experiences with them.

Do you mean this one: www.cinekinetic.com ?

I bought one directly from them two months ago and it works great!

Great! That is exactly what I was looking for. Thanks.
