CXA is perfect for a South Bend 16". I use one on mine. I'm a Aloris believer, I use AXA on the Heavy 10, BXA on the 13, and CXA on the 16". Don't let somebody convince you to get a CA, it's way overkill. If you watch the "bay", you could probably get the toolpost for about $250, if you're not in a rush, and you can find 3 or 4 toolholders for about $50/pc. I do not own a chinese knock off, but have used one...the toolholders were a sloppy fit and there certainly wasn't a precision "feel" to any of it. Some here do say the Phase II toolpost is a pretty good post, but I cannot comment intelligently about it. Aloris parts and toolholders are readily available new if you need them, although I don't know anyone who needed parts. Get the BEST TOOLING YOU CAN AFFORD. It will hold better resale value. PB
