But if you buy good brands second hand, and you know what you are looking at, then it's not such a big risk.
I bought most of my machines new, but I was privileged to have a reasonable-money-no-object position at the time. Now it's very different and I wear an extra sweater rather than put the heating on. If I were kitting out my workshop today I would buy SH without hesitation. But I'm pretty sure I could suss out a machine quite successfully, because I know what I'm looking at. That was not the case 20 years ago when I was setting up.
If it's any consolation, ww machine are pretty basic, simple, primitive machines. They consist of big lumps of cast iron, bearing, electrical switchgear, motors and mechanical arrangements for guiding blades and workpieces, whilst keeping fingers away.
Once you understand these issues, it's a much safer game, as you can assess what is fixable and what isn't.
I realise you have your BS DVDs one the way, and I'm grateful for you custom, but if you really are in a quandary, why not do the same sort of self-education with the TS before you spend you hard-earned cash. You could always sell the research materials second-hand when you are done!
(Although I'd much prefer you to keep them for future reference).
Bottom line - I bought new but now would buy second-hand.
