About to pull the trigger on a TL-2, not being a lathe guy I wanted to see others opinions on the tool changer. They wont sell the 8 tool changer on a machine with a tailstock but they will the 4. I feel like more often than not a person would need more than 4 tools but maybe I'm wrong. So my questions are: Is 4 tools enough most of the time? How hard is it to remove the tool changer and go to a manual tool post if needed (I did find a post via google searching of a guy doing this but didn't go into how much work it was). I have found a couple used 8 tool changers for sale, are they not that good?
