When looking at a used system, what are the things you watch out for?

[Daniel@R2R]

How many of you buy used systems? What are some things you watch out for when buying a used tank? What are some of your best and worst experiences with this?

It helps to see the tank at least filled up for starters. Check the bracing for cracks. Look for scratches in the glass. Id also look at the holes if anything is drilled and make sure holes are clean and would work with your plumbing size.

I ask for leak test, scratches, cleanliness (tells if seller even gave a hoot about the tank), condition of stand (can help suggest if there was a previos leak if there is rot), and cracks especially around bulkheads.
