Thanks for the input guys, it gave me information needed to do a more informed Web search of the topic
Having looked around the Web, this is what I have found.
There are some people who hate the drill press mortise attachment and one guy had thrown 3 down into the woods in frustration.
I have also found people who got them to work well.
This shows some simple quick set up tips.

- don't use the fence as provided, use two bolts to mount it on its own table (a board)
- when you cut, make sure you are cutting on all four sides, or two sides (front and back), not on three sides as this causes deflection.
This one is more in depth

Having taking on board all that you guys said, and done a little more research, I will buy a drill press and attachment.
The drill press is more versatile, and a lot cheaper than a dedicated mortise machine.
Mortise attachments can be made to work and are also cheap.
Thanks again for your input
