im going to try and get either a 10 or 15 kettle or a keggle and my BK. But for now all that has been purchased are the 2 12.5 gal Coleman Xtreme coolers for the MLT and HLT. I cant seem to find and good deals up in the Chicago area for keggles
You have to be patient, sometimes people want $100 for keggles, and sometimes $40, just a matter of timing. Sometimes you can find a good deal on a keggle with a valve and more in it at times. I would just say watch craigslist everyday and brew with what you have, and upgrade slowly. That is what I did. I bought a SS 7.5 Gallon Pot from a store on sale for $39.99 and used that for a long time, then finally found a good deal on a keggle.
Here is how I started with all grain
5 gallon pot HLT -> 5 gallon Igloo Cooler -> 5 gallon BK for months
5 gallon pot HLT -> 50 quart coleman -> 7.5 gallon BK for months
7.5 gallon pot HLT -> 50 quart coleman -> 15.5 gallon keggle BK for months
next brew
15.5 gallon keggle HLT -> 50 quart coleman -> 15.5 gallon keggle BK.
eventually the 50 quart I'm going to move to a 70 or 75 quart.
But as you can see this has been a slow progression for me, you may need to do the same, or maybe you'll find a sweet deal. Cheers.
