I use an Ikea table that can be found in their office section. The different size/colour tops can be used with different styles of legs, all bought separately. Some legs are adjustable in height by just twisting them which is easily done in situ.
The added bonus for me is that the larger size perfectly straddles a UK double bed. As I use a spare bedroom for sewing, this means that the cutting table is using the same footprint as the end of the bed.
I have the same table in a smaller size for the sewing machine. I chose shiny white table tops which means that quilts slide easlily on them.
