Those folding tabletops are generally pretty bad: they're not stable and they shed.
There's a thread on chiptalk about an 8 person table with a reversable top: one side is a "real" table, the other is poker table (unfortunately with a WPT logo) that some people got at Sam's Club for $150 to $300. It looks really nice: despite the WPT and higher price, I might have bought this table over the one I did get.
I'd take a look, if the price is not too high:

After all, this would be a real spare table, much nicer than any kind of folding table!
