Glass is a more expensive option, but I feel that it's well worth it.
Price Payed: $60.00
Recommended? Yes
Pros: I use this one as the primary for my 5 gal batches. Opposed to plastic bucket primaries, with this carboy I can see my beer. It's super easy to clean and sanitize. I can see my beer. It doesn't stain. Cleaning with a brush doesn't scar the surface, leaving it rough. Also, I can see my beer.
Cons: If proper care is not taken, light can definitely ruin the flavor of the beer. I ferment in a closet, so this is not much of an issue for me. Glass is heavier than plastic alternatives. I have huge muscles, so this is also not an issue for me.
