For the new Gen 3 with thermowell and dry hop port see this link
We have stocked the Fermentasaurus, we have stocked the Fermzillas.
Honestly both of them have their flaws and most of those come from the dump valve at the base.
Don't get me wrong, we love the idea of being able to dump out the trub and save the yeast and the dry hopping through the collection jar etc.
But at the end of the day in our personal opinion (and after dealing with a lot of customer issues with them) we believe that it is actually much easier just to get a second pressure vessel without a dump valve and transfer the brew across leaving the trub behind to do what you want with. You can go straight to keg or to another vessel to dry hop and age in.
Want to dry hop in the same vessel at the end of fermentation? Grab a hop bag and 2 magnets, put one in the bag with the hops and use the other on the outside of the Snub Nose to hold it up out of the way near the top of the fermenter till you're ready to dunk them in. Easy, effective, no chance of oxygen or bacteria contaminating and definitely no chance of blocked valves, stuck threads, etc.
Considering these are half the price of the full-featured Saurus or Zilla that isn't crazy to get 2 and you can also use one of the 20L Fermenter Jrs or an ordinary keg for it too.
We love that these fit inside a kegerator fridge for temperature control, we love they have the floating dip tube and ball lock posts you have to pay extra for on the Zilla and Saurus and we love that they fit 30L brews in a compact space.
Win-Win in our opinion.
