The X-2 is $159.00. For a price jump like you are suggesting, then the Stringway ML90, with either flying or fixed clamps, is in play. This is a terrific table-top. For the price, the X-2 is a capable machine. Stepping up to all-metal clamps, the SP Swing is a nice option for $40.00 more. *Really* nice clamps.
The SP Swing is DEFINITELY worth the additional $40. The cheap plastic clamps with the X2 will make you wish you spent the money.
