I have the same model/vintage. The machine in the ad is missing the side arm supports, but the way the 6/12 mounts work it is really more like a 2-point mount rather than a 6-point. Mine was missing a couple, and I couldn't get Eagnas to sell me any, I ended up buying them from an Australian company while I was there for work.
The base clamps aren't great, and will eventually have problems. If you search McMaster on this forum, you'll find a list of parts to rebuild the base clamps, and they will work much better after that. I also had a clamp fail, and replaced both with the three-tooth Eagnas PN-1012 clamps, which are a big upgrade over the ones that machine comes with.
Having said all that, I still prefer it to the Gamma X-2 I had been using. And I've since bought a used Alpha crank machine with a true 6-point mount, although it has its own problems I'm trying to solve, and I prefer the PN-1012 clamps to the five-tooth Alpha clamps. I'd use the PN-1012s in the Alpha but their diameter is just a bit less than the Alpha's, so there is a bit more slop than I'm willing to accept.
One advantage the Hawk 800 has over the Alpha I bought is the base on the Hawk is metal, whereas the Alpha's is plastic, so the Hawk is more stable. Also, when I bought the Alpha it didn't have 360 degree rotation as the table was a bit too low, and I ended up buying washers and a roller bearing to raise it, a problem I didn't have with the Hawk.
