Craig has covered the issue well. I have run autostart Peggy HPNL's, which function identical to the Oly's, on a couple of planes for the last 4 years. Hard to believe, but except when a glowplug went south, I have never missed a start. Can't say that about my Jetcats. I now have one of my Peggy's in my BVM F-100D and one on the bench waiting to go back to Bennie for first check in 4 years with about 50 hours on the timer. I also use Coleman Propane, offboard, but with the solenoid on line to control gas flow. You can also KISS and delete the gas solenoid and control the flow with a flow controller on the Coleman can.

You can run the V2 ECU from Bennie with (4S1P-2300maH) A123's now, rather than the 10 cell, 1700maH Nicad he has been shipping.

I know the conversion is a bit pricey from Bennie with the weak dollar against the Euro.....not sure about exact price now.

I do like the AMT USA feature of a programmable EDT so you don't have to fool with a laptop to change settings, but once I figured the software out, it takes just a few minutes to set up.

I still like the sound of any turbine, full scale or model, during an air start. With Bennie's V2, all you do is disconnect the starter plug from the ECU plug, push in your airline into the air festo on the front of the turbine, and you are back to auto-air start. Those starts are very fast and IMO, sound very cool. Also, if you have driven 900 miles to a JetMeet and your starter dies after your first flight, you can switch to air start in about 10 seconds or less.
