I started brewing with a 6-gallon Mr Beer that I got for Christmas one year back in the '90's. It's great because (a) wide top so it's easy to fill and clean, (b) clear plastic so you can watch the flocculation, and (c) side spigot 1" off the bottom so you can dump straight to the bottling bucket without much (if any) trub.
Then I graduated to a 7-gallon plastic fermenting bucket. It was OK, but the lid seal could be tricky, and I didn't like the lack of visual feedback. It also sports the wide top, but no spigot, so siphoning and all the issues associated with it. But I got rid of the Mr Beer at a yard sale.
Then the fam came thru again on another Christmas and got me a polyethylene conical fermenter, plenty big enough, with wide top, temp gauge tap, spigot tap, and 1" ball valve at the bottom of the cone. I used it twice, I think, before I went into brewing hiatus. I was worried about all those taps and the potential to harbor bacteria. There was no gasket around the lid, and on my second batch I noted a pellicle on the kreusen -- not pleasant to see, and I think I scared myself off of using it.
Fast forward about 8 years, and while browsing a church garage sale I noticed a brand-new (as in unused) 6-gallon Mr Beer, complete with six two-liter bottles and fermentation lock. They wanted $5 for it, and something pushed me to buy it.
Fast forward another year, and guess what I've brewed my last three batches in? Mr Beer!
