He said.. you WON'T need a SS fermenter. Yes, they are available.. but, I'll bet that over 90% of us use plastic or glass for fermenting.
Lots of good advise here. You can turn out GREAT beer from extract. All grain gives you more control of what goes into the wort.. and it can be fresher, ingredient wise. That said, a well brewed extract will be hard/impossible to tell from AG. Def a lot less $$ involved. Some say.. Go for it.. I do AG now.. but, still do extract every so often. It's just quicker and easier. I do, however, check the dates on my extract. It can go downhill over time.. but, not like back in the 60's to 90's. Processes and packaging are getting better over time.
