2002 isn't old or vintage.I agree, all mine have been used.
But the one linked is very old, the original MK25 (2002-2003 vintage) and I would say s600 (2001-2005). They would need servicing and kits $100-$150. The balance chamber may need upgrading on the s600 ($40). Need to know if the MK25 has constant IP other wise the piston may need changing, $100.
Nothing has really changed since then.
Since the conversation has turned to used gear, there is a ton of very good used gear out there for pennies on the dollar, you just have to know what you are looking for.
Used is great way to save a ton of money, especially if you pick brands that you can get parts for and do your own service work.
