Sorry to hear about your back problems, but happy you got better now!
I'm quite new to this, have done about 8 batches in total but I'm really enjoying it and there's so many things I want to try my hand at! I've only done 1 all grain with borrowed equipment, the rest were all kits and I have the same problem with the equipment, it's quite expensive to go all grain unfortunately, but I am sure I will find some way to justify it to myself, hehe.
I might go the malt extract way as a stop gap before making the jump.
Glad to hear you're thinking about coming back to homebrewing, there's a lot of us here on steemit, which is great!
Cheers
