Anyone have any experience with the fermentap weldless mash keg conversion kit? Available at morebeer. This option is quite a bit less expensive than some of the other options out there. With that said, I don't want to have to go back and rebuy a better quality item if this doesn't work out. The other option I am looking at will cost nearly twice as much, but is probably of better quality. The mash screen on the fermentap has a 10' diameter, others I have seen are 15'. Is 10' too small? I will be using it as a direct fired, recirculating mash tun for 5 and 10 gallon batches. Thanks.
