I just got a LN 12" Delta at an auction for $80.

Ebay has a mortising attachment locally. Do they work, or are they just
aggravation?
I have never actually made a motise, so it is hard to say how many I will be
doing.

Works OK for me. I also have the Delta mortising attachment. It does
what it says. I would bet a dedicated mortiser would make a cleaner
hole, but who cares? You can't see it anyway.

For the weekend hobbiest, I think it fits the bill.
