I sold my ML7 because: 2MT Headstock bore was often too small;, (later models overcame this limitation) did not like how it shook when I used the Rodney milling attachment.
Thirteen years ago, the price of a new Super 7, (ca £8K) with Norton box , Chucks, and Steadies made me feel faint, and could not be justified. The successor is a larger Chinese lathe with MT5 spindle, hardened bed, Chucks, Steadies, and a retro fitted British VFD came to £2K. It weighs 300Kg and will swing 12 over the bed, and 18" in the gap(Not yet used)
Like any machine, it is not perfect, but it has done all that I have asked of it, so far, despite my carelessness.
From what I read, small Chinese lathes are not tolerant of abuse, and Model Engineers tend to achieve things that the designers of the machines never envisaged.
You can do small work on a big lathe, but not the other way round.
FWIW, my advice would be to choose a lathe which is larger, and heavier (more rigid) than you initially think that you will need. The extra outlay will buy a lot of peace of mind and confidence. If you can find a British lathe in good condition, go for it. If not, do look at more recent larger and heavier Chinese machines. My preference for changing speeds would be belt or gear head rather than original equipment variable speed drives. BUT that is just my prejudice, although I continue to be happy with my British retrofit VFD.
