Hi Nige
I bought an SX2P from Arc earlier this year. I can only speak most highly of the service from Arc, the machine was delivered when promised, in proper condition, and when I had issues a phone call resolved everything without trauma. I was sufficiently impressed to subsequently purchase my lathe from them.
The choice of the SX2P was firstly weight, my workshop is in the attic so getting it up there was a large consideration and even with two of us a bit of a struggle.. Secondly cost, I spent £780 delivered which is a substantial enough sum, but I have since spent in excess of that in tooling, some of which might be considered luxury if your on a tight budget but I justified it to myself nonetheless. Thirdly but importantly ongoing support from the supplier, I don't think Arc are going to disappear. I've no doubt other suppliers can do as well.
In essence I think the SX2P could do most of what you wish however in hindsight I wouldn't recommend this particular machine for these reasons. The arrangement of the head movement via a rack on the column, both for coarse and fine movements, is sub optimal, especially with the counter torsion spring. A machine with a quill is IMHO necessary. It does work but not as well as it might. The lack of X travel stops on the table is undoubtedly a cost saving but could be an issue. The X and Y locking screws are a joke, I'm making something better.
Further thoughts, if you don't have any existing tooling to match in then get the R8 spindle taper, getting stuff out the spindle is much gentler, Don't bother with a tilting column, tilt the workpiece, it's much simpler. The brushless DC motor with a belt drive is very quiet.
This might sound as though I have aeons of experience, but really I'm just a beginner. I found Harold Hall's book most helpful and yes I did read it before I bought the machine.
Finally I think the hi torque version of the SX2.7 is where I would go if I were doing it again, it's not much smaller than the SX3 but is £460 cheaper.
Regards
Martin
Just remembered, be prepared to do a little lapping in on the dovetails and gib strips, they're a bit unfinished as supplied which seems to be a Sieg issue rather than anything to do with Arc. The quality and application of the paint is dire.
