Anyone use the Exo-Terra large/low (equivalent to 40gal) tanks that have the front opening doors? The pet store clerk actually shunned us from this kit that comes with that, maybe the right reasons would be it had poor parts to come with it, but that wasn't as she explained it. Merely a matter of cost that the regular tank was just as effective. But if making life easier > cost we might actually lean towards this exo terra tank. Anyone have any experiences with them?
