I just ordered a pair of stainless Engines on the fasttech Thanksgiving sale: $18.42 each. I'm eager to check out the top airflow and the big fill port. They'll be my first 25mm tanks, but should sit nice on my Cuboids. Those are currently hosting my Bachelor II tanks (another nice hassle-free dual-coiler), but I threw in a pair of EVIC VTwo Minis in the new orange and blue colors to handle those.
Thanks for all the helpful tips, folks!
