As for comments on the spiedel, check the posts under reviews. I did one there for the spiedel 60 liter fermentor. Love it. I still have glass carboys for secondary , dry hopping, wine etc. The 60 liter works perfectly for double 6 gallon batches (46 liters), with adequate headspace for foam so no blowoffs required. I only make 46 liter batches now that I have this.
Just don't scrub the food grade plastic with a scrubbie or anything that scratches, use only a soft sponge to clean. The spigot works perfect for transferring bottling or kegging if you fit a 1/2" clear hose over it. I have done complete fermentations in it for 3 weeks and have done secondary fermentations in carboys after 4 days with good results both ways.
