I'd say at least $3000-3500 these days. Wish that weren't true, as it's ~$2K more than I once paid in the late 90s, but that's what I've been seeing in recent years. I bought one 2 years ago for $2500 that needed some tweaking to work well, and still needs new drop targets, but had a good playfield and cabinet, perfect backglass, and working but noisy say-it-again board which I updated with a modern replacement. Purchased a CPR play field to go with it (but not installed yet), so without labor that lands the price in the range I'm suggesting. Of course, it could be even higher by now, but there's a ballpark for you.
