The Classic II seems a bit more challenging than most, because there's one or two surface mount capacitors in pretty tight spots, and I wasn't able to get in there with conventional tools. So far, this is what I've spent on Classic-related items:
Classic II, free + $20 shipping
850B SMD rework station $100
New capacitors $10
Solder paste $39 (still need to buy)
So, almost $170 to get things up and running, not counting labor or any further complications. Granted, subsequent overhauls will be a heck of a lot cheaper.
