the benefits of these simple units out way the the complexity of any other units. A mag produces mutiply spraks at each ignition cycle. This is something that after marker units try to copy via electronics.
so keep your mags serviced correctly and you shouldn't have any problems and the cost saving place over the bar at your aero club
And what cost savings would those be? The $8/hour penalty in extra fuel burn by running mags? Or the 2 X 500hourly inspections you'll need? Or the $20/plug cost of an 'aviation' plug vs the $2.50 automotive ones most (at least, most experimental) EI's can use? Or the extra 5+lbs you'll forever be lugging around due to the heavier mag housings? even taking away the cost of the actual 500-hourly inspection that's at least $4000 in fuel saved. Add in a pair of magneto overhauls (at $1000 ea) and that's what, $6000 saved? What possible cost advantage is there to running magnetos over EI, if you did not already have mags installed?
The only problem to running EI is a down-route failure. You may not be able to simply drop a replacement magneto in and continue your trip, but a complete extra Pmag is only $2000AUD. And can be installed and timed in under 15 minutes.
