I was just in the same situation. My wife's folks had a huge stack of mint condition 78s lying around and gave them to me when they moved a couple of months ago. My VPI has no 78 speed, so I hit eBay. Turns out that there's a guy who lives very near me who refurbishes old Dual tables. This individual is a fanatic for condition. Seriously, I now have a 40 year old Dual 1215 that looks very nearly new...all for $82. Had to add another $80 on top of that for a good cart with conical stylus (Grado 45C), but I was in business for not much money. The whole thing sounds pretty damn good overall. Here's his eBay 'Items for Sale' if you want to take a look:
