My vote would be older kit in the main, when it comes to classical type machines. Dim saws, bandsaws etc. I have had both and now most of what is in the workshop is old Robinson, Wadkin etc. But would agree, wide belts, panel saws, etc are all far better now than they every were. As is extraction of course, most can be improved in some way, so i have never let this put me of. I also have a couple of Felder machines which are okay, but not something that would last a lifetime in a pro shop, where as all the classical gear i have, came from other shops and in the case of a 1.25ton robinson dim saw, a boat yard. All are quite some age, having already done 20years plus service, the guys using them never tended to go about their work with kid gloves, and buy the accessories plastic shine polish, every inch is adjustable for any wear, and in the case of parts, when the need arises it is a case of having something made up, which is not that hard. I recently had Prestileys make a new gib for the saw after it cracked on the bolt line. Cost was around £70.
Really depends on want you want to buy.
