I just use regular buckets and glass carboys. I've been eying that new fermentor from Northern Brewer. My biggest concern is that if the lid breaks or gets lost how would I replace it? With a regular carboy I can just throw any old bung on it.
I also really like the way the Speidel one looks and it's feature packed, but expensive for plastic.
The new Coopers vessels look good, but all the ones I've seen are very expensive as well. Their website advertises a 34 liter one for 49 AUD (43 USD) and it's plastic. While I'm sure the features are nice it's hard for me to justify buying it when I can get a 7.8 gallon ale pail complete with airlock hole and rubber gaskets installed from my LHBS for $7.99.
