Gosh wish I had seen this post earlier. I have been hymhaw'n all week on buying one as a portable for my QT when needed and cycling a new tank for myself or a friend. I finally broke down and bought one last night at Pet Solutions for $50 plus $8 shipping. It was off $5 with a coupon for orders over $50. I think would have defiantly offered $35 plus $7 USPS shipping would have been a fair offer. But at that price its worth more if you keep it as you can always use a portable filter that's capable of cleaning a 50-70 gallon tank.
