If the glass isn't badly scratched or have any chips, its a reasonably good deal. If it had glass canopies, it would have been a quite good deal. Canopies and stand, excellent deal.
I sold a 75, glass canopies, light, stand, two HOB Penguin filters, and sand for $200 a few months ago.
The glass looks pretty good, so I would have definitely considered it if I was in the market for a 75.
