I bought the Marineland - Top fin, 120 gal. five foot tank from Petsmart about eight years ago. Tank / stand combo was $300 - Black Friday sale.
It's held up really well.
I prefer the five foot 120 over the standard six foot 125 gal. It's a little wider & taller, making aquascaping easier, giving the fish more space to turn around.
It's really noticeable how thin the standard 125s look. Big fish (12" +) have distance and height but little lateral movement especially with any deco. 150 longs are a sweet compromise if you can find one. I've only seen a couple.
