You can buy a much better grinder for about the same money.
That one is a hobby built unit that would not last long. Wrong motor for one thing (and positioned in the worst possible position).
An Ickles grinder ( same unit as the TKS D-5010R) is $425 from TKS, and is much better than that unit. You don't hear much about them, but these little units are quite portable and work well as an entry level grinder. Flat platen and a 6.75" contact wheel.You can turn it around and use the 3" idler as a small wheel. 2.5X48 belts, 1/2HP TEBB motor.Mount it on a hinged base plate (two door hinges and a piece of plywood) , and you can flip it up to be a vertical unit (or make it flip sideways to be a horizontal grinder).After you get a bigger unit (we all do eventually) use it as a dedicated sharpening unit.

This post reply is not regarding the ebay post, but showing how poorly that unit is designed. This is done for the educational purposes of those researching grinders.( and thus is on topic for this forum)
