I've got an 8X10 from the folks in MattKings link. Still haven't used it BUT there's no reason it shouldn't
work right. If weight is important get a weight from them, the 8X10 is just under four pounds.
It isn't a beautiful piece of work by any means(seems to be 1X2" and 1X4" pine) and all the joints are
butt joints assembled with nails. I got this used(lightly) and one of the joints had
separated so I put reinforcing metal brackets in each corner. The smaller cameras may be
less crude but very workable.
