I found the specs for the two tables, and yes, they are pretty similar, but $100 less I'm gonna have to go with the numarks, unless I could find the vestax tables cheaper on ebay.
Numark TTX-1 Specs (source)

Vestax PDX2000 Specs (source)
Starting torque: 2.0kg/cm
Start up time: 0.5 sec (33 1/2rpm)
Rumble: -78dB (IEC 98 WTD)

Like I said, they're both pretty good tables, but Numark has yet to do me wrong. The difference in the majority of the specs is minimal, but the price difference isn't, and thats what gets me.
