Tom, I don't have a good sense for what machine packages fetch, or should fetch, or depreciation, condition, parting out etc. Its not really my jam.
I just said the current cost (of accessories) would add up. As in compared to a bare machine. Just shoot'n the breeze. Spit-ball numbers:
Align-X $500
Align-Z $550
Mitutoyo Quill DRO $300
Gerardi 6" vise $1500
Vertex RT $600
3 Mitutoyo indicators $300
3 Mitutoyo mics + stand $350
That's what $4100 so far, sans GST + shipping, sans phase converter, ok vintage DRO, drawer cabinet, gage block set, hold-down set, cutting tools, collets, drill chuck... yada-yada rest of the stuff.
I'm not speculating on value or he will get asking price. I'm just saying 'it would add up' if someone had to equip an otherwise bare machine.
BTW if you ever need to unload your 'typical Chinese' Mitutoyo or Gerardi stuff for deep discount, I'm your man! But it must be new condition! LOL
