You should study whether the locking method used on these posts is really to your liking. It would appear that you have to scrounge around for an allen wrench to clamp the dovetails onto the tool block. This could get a bit annoying if you have a lot of tool swapping to do.
The better ones have a large handle on top of the tool post to lock the tools with a quick 30 degree push of the handle.
The only thing I don't like about the square toolposts is that it is not handy to get the tools at other angles other than 0 or 90 degrees. And, if you went to a little trouble to align the toolpost already for holding a drill bit parallel to the spindle axis, you don't really want to just yank it loose and swivel it.
Thus, even though I have a square toolpost on one small lathe, I prefer the 40 position quick change toolposts that allow you to clamp the tools at many convenient increments. But, these are quite pricey. However, they are vary repeatable, and good for use on a cnc, if you go that route.
