Oh yeah, sorry man. I was in the same boat as you a couple months ago. I wanted to get into this cheaply. I did quite a bit of research on the brew kettle. I ended up deciding that I wanted to get the "best bang for the buck", stainless not aluminum, and just get one large enough now, so I wouldn't end up buying bigger one down the road.
I ended up buying this one and after 4 brews, I'm satisified that I made the right choice and it will be big enough to do full boils when I go to AG. It shipped free with Prime. Good luck, Cheers!
