By most accounts, Tormach machines are a good value. I did research them heavily at one point. I was looking hard at the 770. I wound up buying something else for the rigid tapping feature it had and have been happy.
I might have been happy with the 770 as well, because I did have a tapping head at the time. I do buy almost all my tool holders from them and I can tell you that the experience was just as you would like to have from a company that cares. I don't think you can go wrong buying from them.
Good luck with whatever you choose.
