I recommend electric
Here is an ALL BRUTE FORCE thread
(mine is on page 2)
I replaced the gas burners with 9000W electric heat as it is much faster (10 gallons from 50F to 170F in 20 minutes), needs no venting and is more economical (full brew session, heating strike, running the RIMS and the boil for under $2)
I replaced the PIDs with a BCS460 and married that with a wireless bridge so that I can control the system wirelessly from my PC. Read, no switches or control panel...
I replaced the March 809s with LG 3-MD-HC pumps because they have 2x the flow of the March and prime much easier IMHO. They are also WHISPER quiet, my 105CFM muffin fan is louder than the TWO pumps when they are both running!
