Thanks for the eBay tip, David.  I ended up making several bases from 1/4" thick poplar wood yesterday (see photos) but I remain on the lookout for ready-made bases. 

Normally I would put rubber feet on the bottom but this wood is nicely flat/true.  After staining/sealing it almost has a "suction" to the tabletop so I may forego the feet.
