I have, and regularly use the mortis attachment.
It will get me by until I can afford the Powermatic or General heavy duty mortiser.
I will say this, for a couple mortis's, it's a pain. I cut shims of scrap wood to align the bit and the fence.
But the worst thing about it is the stinkin aluminum handles and the iddy bitty teeth that meet the steel bolts. All 3 striped the first time I set it up. So off the hardware store and bought some hardened bolts that I can use a socket on.
I emailed emerson on the problem, but never got a reply if there was a fix or not.
Any drill press mortiser isn't easy to set up or use, but does get you by. If your heart isn't into spending almost a grand for a heavy duty floor model one, do some researce into the table top models. They run around $250. Pick the one you like the features it has for what you know you'll be making.
