I have tons
Few months ago I picked up 2 75g tanks, 2 stands, a 10g sump w a smaller wet/dry, all plumbing, couple heaters, lights, hob protein skimmer all for $120
Got a 55g tank, lids, lights, 400w hydor heater, penguin 280, xp4 and tons of decorations for $20 at a yardsale
I just got my 300g deep dimension with corner overflows, plumbing, stand, canopy, lids, and 2 brand new quiet one 9000s for $1500 ( all of this was bought new a yr ago and had never seen water, the pumps were still in box w the recepit)
Free 55g tank for my sump
Another time from this site, got a 125, stand, canopy, lids, lights, 55g, gravel and decor for both, xp3 and ac70 all for $100
Another time from cl I got a drilled 75g, stand, lids all plumbing, mag 9.5 and marineland tidepool sump for $120
I eventually sold the 55g lids, lights, heater and penguin 280 (that I got from a yardsale) to a friend and took it to his house for $20. About 6 months later, he called me and asked if I wanted the tank back. I said "Sure", but refused to let me pay him back the $20
ALso, the xp4 that I got in the yardsale deal was returned to Petsmart ( I had just bought a brand new one a week prior to buying the used one). They didnt ask any questions and gave me $265 store credit. That was my way of saying "F@%K you" to big business that are overpriced.
