A lot of it will hinge on the inclusion/condition of the cartridge... in your case, a MMC3... decent, middle of the pack cartridge, but nothing lasts forever and there was little comment made on its condition. If needing replaced... Soundsmith. It also appears that there are cleaning marks in the perspex, or at least, poor pics. ++++EDIT++++ the platter looks dirty!
How bad do you want it? At $300.00 I would start looking for other BG's! (you are at the level of a really nice 400x, but perhaps not a 4000 -if you can find one!) What do you intend connecting it to?
