The ES-1 [$425] the SP-303 [$319.00] SU200 [$369]

If I had to choose a "buget" sampler I would get the ES-1, because it's more then just a "Phrase Sampler". It can chop up your beats and you can always play your samples in time to an external MIDI device -- without the pitch chaging. Or tap the tempo to beat match with your turntables.

It also offeres you the SMART MEDIA CARD option, for backing up your samples.

Again, good luck.
