I was just about to purchase new glue and looked into this deal. It seems that the single gallon bottles are a few dollars cheaper per gallon than the five gallon bucket. Or, at least in my area, CA.I always use the TB II just because I don't need the extra water resistance and it's cheaper. You can get a 5 gallon bucket on Home Depot's website and get free shipping. The best deal I've found.
I don't have any qualms about using Elmer's white or yellow (carpenters glue).Kind of a side note...I run a decent size hardware store... most of the tallk about glue on the forum keys on TB. I use as much elmers as TB but I find that shelf space in the store has followed the forum. It is now about 10 to one TB.
