I was looking at the Brupak 'Brewer's Choice ESB' as it looks like a good midpoint between kits and extract brewing.
The pack says it uses 'Tea-bag Technology' and it looks very appealing.
I'm not going to have the space or cash required to go FG for a very long time, but it looks like the best thing if you're limited.
Really would like to hear of anybody's experience with these things...
