Buying used sump

[Meyerbj81]

Found a local trigger 39 emerald sump for sale and had a couple questions. Anything I should look for when buying a used one other than obvious cracks, deep cracks etc etc? Also, what would you guys consider a good deal on price for a used one? I’m finally on the winning side of a long Dino battle and am ready to sink a few more dollars into my tank. I already have a diy 40 gal breeder sump that functions well enough for me but like the looks of the trigger sump.

Cracks, leak test it, seam separation and heavy scratching
