If you appreciate great craftsmanship IM is the way to go. My 25 lagoon is heavy with thick glass, clean silicone and design very well. I had jbj before and totally different tanks. Worth the money IMO
I am impressed with IM tanks... I'm about to pull the trigger on the 30L but i've seen a few in person and it looks quality for sure. I doubt you'll regret getting an IM
