No worries, thank you for the courtesy.
Er, I've never really bought a tank.
I have an aqua one I think it is, black silicone, the lid cracked and broke. Plastic gets brittle with age. I've had it 6-7 years or more but not much, it was a second hand freebie. The other manufactured tank is a 65litre Hagen. It's nice. Again it was free. I think I'm the third owner. It had no lid. Both of these tanks came with stands. Basically they are all the same, chipboard veneer, real money stands are solid wood.
One tank has plastic trim along the top the other one doesn't. Then lids are either fitted with or without lights. The stands last long enough before they start looking bashed in. They certainly lasted me long enough. The Hagen tank still sits pretty on its stand, the aqua one stand I destroyed and disposed off, it was in the way, it still functions but I didn't need it anymore.
Some people now use box steel, no experience with these as a stand, if treated it's probably better than wood.
I bought three tanks off a guy but they were DIY they are good, the rest including my first tank, I built myself out of a mix of laminated and regular glass, naturally I think they are also good! Depth is what costs money as deeper tanks need thicker sides.
What I'd look for is surface area at the top of the tank, that's the most important thing. Just pick a finish you like. Maybe one with a badge on that you like too! I like the Hagen badge it's subtle, the aqua one badge fell off.
If it holds water it's a tank, or it has tank like potential, That's my view.
