I would have ot give Tormach a ref also. They really stand behind there product and do all they can to help there customers. The machine will do about anything you need a hobby/production mill to do. Not the fastest machine around but very stable and with the right toooling and aproach it can get the job done, over and over again.
Now not knowing about the electronics in these mills is nothing to be worried about. Infact even with a turn key setup in time yuo will be forced to learn how these systems are made/built because you will have to service the machine. Now with that said it still can be a benefit to go turn key becuase there is plenty of other stuff to learn and you can be making parts while its going on.
The biggest question I find is how much money do you really have to invest. Is ten grand your limit, or is there more even if it takes a bit of time. To truely get a turn key Tormach and really get productive with it you will spend more. Tooling, work holding, software, measuring equipment, and more tooling(always replacing bits & needing new types) will take way more than you expect. BUt you may have some of these things already.
Still alot depends on many things, and you can start slow and build a little at a time. One problem I see is your wanting to go from one extreeme to the other in your work. You need rigidity, but also high speed spindle. It will be hard to find any machine in this price range that is not going to have to be a bit of a comprimize to do these jobs. WHat you really need is something like a Sharp Mini mill, or a Haus mini. Ofcourse the prices jump a ton to even think like that. But that would be the real anwser to your work needs.
Now dont get me wrong, the Tormach and a few others will do these jobs you need but speed and how you aproach the jobs will be according to the limits of the machine and you will have to deal with this. The TOrmach is a pretty good comprizing setup that will get the job done. A Optimum BF-46 is another mill which I fill is a slight step above the Tormach ( stronger better built) in several ways. But you cant beat the Tormach's backing or track record. It will last, and you would always have good help from both Tormach themselfs & the community. A lot of these machines out there with a lot of expeirance. This carries a lot of weight for someone like yourself and it will be worth having this help and expeirance there with you when you start trying to do work.
There is alot to this stuff, even at its best you will be finding that you need info/help pretty often. This is where the Tormach really shines, there is always someone with a anwser to what your trying to do, or fix/figure out ( its a CNC machine, yes you will be working on it at times). Newer tooling coming out these days are really helping these lower powered machines make better progess. All though it may be expeincive the right tooling will help a machine in this range perform alot better than a benchtop could be expected to do. Tormach themself have started coming ouot with some affordable tooling that really works good with a machine like this but as you start perfecting a job and it gets to be something yuo will run for a long time them going on up the price range can really make a big difference. Specialty end mills when working with tool steel can get pretty pricy, but it can pay for itself in time.
