I picked up a 4x8 steel for 55.00, it's what I used in my stickburner. I was able to pick up some SS expanded metal "drops" from a local fabricator for cheap. Full 48"wide, various lengths, none over 16". Made a bunch of charcoal baskets for UDS's out of them. You might try going that route if you want SS and tacking them together to get your size.
