Yes I was asking you. Sorry, new to the site. Thats great. I used to have a 150 gallon with just a red-tiled cat and a peacock bass, but had to sell it not too long ago.
There's a difference here. Let say the BMW price starts at $55,000. Now, someone buys the BMW, drives it around for a year and a half. When they decide to sell it, it has 150,000 miles on it and it has normal wear. The person says, "Well, I paid $55000 for it and its only a year old, so it is easily worth $50,000." It doesn't work like that.
Fish tanks appear to closely match the electronics market, we'll say speakers for example. You buy it for $100. Once you want out of the store, it is now only worth $50. Then, once you hook it up and play it, it is only worth $25. Granted there is a little variance in supply and demand, but the principle stays the same.
I would not pay, more that $200 for a 125. I would pay up to $150 for a bare tank, but you will neve get me to pay more than $100 for a cheap store bought stand. I would rather make it myself. The tank I am looking at tonight, guy wants $100 for the tank, $200 for the stand. $300 total. If he will not sell the tank and stand together for $200, then I will just take the tank. Stands are not worth $200 IMO.
