IMAO, homebrewers I meet are usually DIYers and prefer to build it themselves (and add any customizations). I like the plans idea and you could sell them for more than $10. I'd probably pay $30. Sites also exist that will watermark the plans in case they are shared. Maybe you could resell all...
Great! Thanks for the reply and proof of concept. Sounds like it is really holding up.
What size tslot did you use?
Guess I'll just have to eliminate boil-overs :)
