Help Finding Sterno Heating Racks?

Hey Everyone!

I've looked high and low all over London for those "disposible" heating racks that you put food in for parties to keep them warm.  They are metal and you use the foil pans with them with the sterno heaters ?  Does anyone know what I'm talking about or where I can find them?  In the states I would normally just go to a Party City or even a dollar store, but I can't seem to find them here.  I can find real stainless steel chafing dishes, but that's just not practical for my little Superbowl Soiree, OR I can find warming plates, but I'm only here for another year and a half and am trying to minimize the electrical items I buy.  Any help or input would be greatly appreciated!!!

i found some at tescos around thanksgiving time.  they were non-disposable but were like £3 each or something.  check there.

Would lakeland carry something like that?

yeah- they do carry that sort of thing- but they were expensive.
