 I have the Reiff system on my Lyc IO-360.  Absolutely maintenance-free.
 Heats uniformally and quickly.  If I am near the hanger I'll plug it in
 overnight but if not then first thing when I get to the airport.  An
 hour later even at OAT 15F it's ready to roll and fires on the first
 turn.  I installed one on my new Cont TSIO550 also.
