I almost bought a Ryobi at Home Depot where they are listed for $149.99; but decided to spring for a little extra and get the one from Harbor Freight.

This puppy weighs 125 lbs so it is not portable if that is what you are looking for in a benchtop. The thing that finally sold me on this unit is the 16 speeds, some of which are very slow, so I could use large Forstner bits. If you don't have a HF store close by, the Ryobi is probably a better choice as shipping would put it well over $200.
If you are patient, this DP goes on sale from time to time and if you can catch a 20%$ coupon at the same time, it can be had for about $130 plus tax.
I agree with those who comment that a floor model is generally a better choice. In my shop, however, I have more table space than floor space so the bench model was the better alternative.
