For what it is worth, we went completely Spieldel two years ago based on our experience with the first 60L we bought 4 years ago.
Being "Thrifty" (cheap), we have built and been using a home made all electric 2 vessel brewing system for the last 6 years. Initially it was a 5 gallon system and our Glass 6.5's primaries and 6.0 glass secondaries were fine, old and well used but fine. We setup and brew in the kitchen using the range hood to control the steam and easy access to to the water filter system, sinks and drain. We ferment in a back bed room which is our "Beer Room" with shelves etc for equipment and supplies and a home made 8 keg 2 tap keezer. Ok, Ok, The Princess also stores all of the inside holiday decorations and has a pantry shelf for packaged goods overflow..... Happy Wife.... Happy Life ;D. We Cold Crash our secondaries in the garage for at least 2 weeks before kegging. We have 24 kegs so the full and carbonated kegs are also stored in the garage. We do this because we only brew in the winter, and now that i finally retired, we live on the boat all summer and try to brew enough to last almost all summer!!
The point is that we have to carry the glass 6.5 to the back room from the kitchen, then move to the the shelf across the tub (we live by the lake ... no basement) to rack into secondaries and then cary the secondaries to the garage. When we keg, we carry the secondaries from the garage to the the tub to rack to the kegs. A lot of carrying VERY Heavy glass carboys full of beer through the carpeted house!!!! Things really picked up when we upgraded the brew system to 10 gallons, and stared brewing 2 days a week!!! ??? We had to split the batch into 5 gallons to use the glass! A lot of work. A lot of Risk, and VERY Awkward to handle. We certainly weren't going to stainless. Most plastic were conicals and carrying an 80+ pound conical didn't seem like a good idea. So the best option was to take a chance on the 60L Speidel. It worked great! It was the round style, huge lid for easy cleaning!!! We bought the small plastic dolly from Harbor Freight and just pull it around. We did have to use the pump to transfer into the secondaries. Wonderful!! 8) Bit we still had to carry the glass secondaries to the garage and back. :-[
So we went all in on Speidel.... We bought four 30L that we use and secondaries and added a rectangular 60L primary and another dolly!! 8) We couldn't be happier!! All are very rugged and adaptable as you have read in other posts. The secondaries are very easy to carry securely back and fourth to the garage etc!! Our only wish is that the rectangular 60L had been available as our first purchase! Much easier to handle and clean. The big lid on the round 60L can sometimes be a pain to handle and seal!!
We plan to continue brewing 10 gallon batches two days a week every winter adding maybe 4 more kegs. I even toy with the idea of replacing the round 60L with a rectangular and sell the round one! This was a bit long for a post. Sorry, if you are interested in more details of our brewing system etc. Let me know by email and we can share pictures and offer any explanations requested!!
