I have a Ryobi 12" benchtop from HD. $150, also got a Delta mortising
attachment for another $50. This thing is indestructible, variable
speed, never bogs down even with 4" holesaw in 3/4" plywood. Also use
it for metal, sanding, grinding, manual mortising. The great thing
about this dp is the head can also be turned on column. The base is
clamped to the bench at one end, so if I need to drill the end of long
stock I just swing it off the side of the bench.
