Hey Red,
There was a good article comparing chain morticers in a recent issue of "Timber Framing". Contact the TFG store or office to get back issues. Better, join and get all new issues coming up.
I like my 24 yr old Mafell chain mortiser, smooth, powerful, steady, comfortable and fast. Use it freehand or with either of two diff fence/brackets. A great pleasure to use. I started my first TF w a hand brace and bits, bought a used 1/2" elec drill for $15, moved up to Milwaukee Hole Hawg drills, Then sprang for the Mafell in '85 or '86. Always good service from Denny H at Mafell NA too. Later bought a Makita as a less expenxive 2nd mortiser but sold it last year.
