The stainless Guten will last far longer, and fits in a fridge, Snubnose could get 3 three for $10 more,
Fermentasaurus proper fridge space a problem and when the new one comes out you will end up buying the adapters to modify one you get now.
If I was buying now I would wait till the end of July for the Guten, comes with a racking arm and draw off tap and if you wanted to pressure ferment half a dozen little G clamps from Bunnings I would think hold the pressure, or even better there might be somewhere to buy a drum clamp ring the right diameter.
What time was you in there? I went in for a m/f 1/2" elbow and 2 people came in asking about the Guten Fermenter, that was around lunch time.
