Hello Dark Knight,
Sounds like the Index mill is about the size of a Bridgeport. The accessories are a good deal. The #9 B&S taper is not "bad" just tedious to remove when stuck. They are still available from selected sources but not the Grizzly-Enco big box store sources. Check Kitts Industrial Tools (1-800-521-6579) in Detroit. It was a fun place to shop when I lived in that area 30 years ago.
Another B&S taper sources is Production Tool Supply in Warren, MI and elsewhere. This is where I got my B&S #9 taper endmill holders for my US Machinetool Cincinatti mill 25 years ago. I got a 1 inch toolholder for big mill shanks.
Endmill toolholders use a setscrew to lock in the cutter rather than collet squeeze. Mo better especially for the sticky B&S taper. The B&S taper tooling is getting scarcer. Perhaps ebay may be a handier source for these.
Check all sources before buying any mill to your satisfaction.
