Does anybody have any good or bad opinions of the Delta mortising attachment for drill presses? I'm a hobbyist, so I don't need extreme speed or accuracy. The attachment looks clumsy and awkward, but the tool guy at the local Lowes says it works great (same thing he said about the $40 wobble dado set...). I've been needing a mortiser, and I'm tired of making them with chisels. Are the dedicated mortising machines a better option than the drill press / mortising attachment? I would greatly appreciate any feedback. Thanks!

Also, Costco has a 14" Jet floor model drill press for $199. Is that a great deal?
