I agree with everything Bob said. Unless price is no object, you are not going to find the "perfect" mill. If you are posting here, price is a big consideration. Sooner or later you have to put some $$ down and get on with it. Tooling is another significant consideration. If the only tooling offered are those collets, then you are going to need some basic items to get you started (more $$).
What does the rest of your shop look like? Is this a good fit with what else you have and what you want to do?
I don't know if that machine has power quill feed (nice for boring) or a back gear (nice to have a very wide speed range - especially on the low end). I don't see any table feeds. It does not have the head "nod" (which I feel is a benefit to not have the nod feature). It does have the slide out ram (very nice). The 3 phase motor is nice - easy to make it variable (and give you a broader speed range).
As part of your learning, you will figure out what features you would really like to have (no doubt my list is going to be different than yours, or anyone else's).
Of course there is risk on your purchase. When you (or your estate) sell that machine on, you will get something for it - so the entire purchase price is not at risk. I don't really understand why, but many folks are glad to pay that much for a much inferior machine, just because it is new (and in a week it won't be new).
I got my Cinci real cheap because it was dirty, grimy and could not be tested. These machines, especially the older industrial machines are very tough and so designed that even with a bit of wear, can still give quite good results. Any machine can be trashed, but for the better quality machines, it takes some effort to destroy it - without being obvious.
You are learning. The purchase, set up and figuring out what this machine will do (and what you would like it to do) are all part of the eduction. I bought my first machine, a lathe that every one said was too much for a beginner, over 30 years ago for $9500. I probably paid $2500 too much. I have no regrets - it got me into an awsome hobby, I've learned a great deal. Looking back, I'm glad I jumped in with both feet. I have since bought 4 more primary machines and several smaller ones and all put together they don't add up to what I paid for that first one (that is all part of the learning). I still use that first lathe - a lot.
Do the best you can to check it out. Write back here and ask more questions. If all looks good, then make an offer that you can live with, but you don't mind walking away from (happy if you get it, a sigh of relief if you don't).
