I'm in the exact same boat as you. I've been out of work (well, now I'm a "stay-at-home dad"). Going AG definitely helped lower costs since I inherited pretty much all the equipment I needed. I have been reusing all yeasts, either by washing or just jarring up the slurry, which saves ~$7 per batch. My last couple batches cost $25 each, b/c I reused yeast and already had some of the hops I needed on hand. I just went balls out on ingredients for an IIPA though - just had to do it - damn hop addiction!!!
Another thing I did was to put a "beer jar" next to my keezer, so my friends can contribute to ingredients for future batches. I've actually gotten more than expected - 2 buddies put $20 each right away, so that's almost 2 more batches right there. I guess they appreciate not spending $5 a pint at the pub, and my 4 on tap are just as good or better.
