Great price. I don't own one but seems worth it for someone that has been looking around.
JB, PB and others are selling it for $129. Maybe you could try price-matching with them if those stores suit you better?
Was $49 last time this keyboard was posted on Cheapies.

If you haven't already, could take advantage of the Primate 14-day trial to get free shipping. I did it this morning for a feeding chair I got MA to price-beat.
