best self-launcher propulsion system?

I am curious what group members with experience with self-launchers
regard as the best propulsion system (currently) in terms of in-flight
restart reliability, maintenance, safety, and other operational
factors (e.g., vibration). *Of course the electric Antares might win
on all counts except for range, but it is out of my price league.

NEW:
Silent 2 ELECTRO FESL
Front Electric Self Launch
ease of operation and peace of mind

greater reliability when compared with any internal combustion engine
secure and instant start-up; the motor requires no warm-up prior to
application of full power
absence of vibration; the only moving parts are the propeller and the
rotor
maintenance is essentially unnecessary
nose-mounted motor is on the fuselage center-line and thus has no
forward pitching moment
to create take-off difficulties as is typical of pylon mounted
propellers
no loss of motor power as a function of altitude; performance is
unvaried with respect to atmospheric conditions
motor use is extremely simple; no raising of a pylon, simply turn on
the master and apply power
absence of aerodynamic resistance (engine pylon, etc.) and
consequently better flight performance
simplicity and uncomplicated use of the entire system, when compared
to solutions with a retractable
no change to the aerodynamics when using the motor
no change to the center of gravity when changing between powered and
unpowered flight.
prop located in front of the cockpit and safely visible to the pilot
at all times
availability of extra electric energy for even the most well-equipped
instrument panel
lowest price for a new glider
can fly more then an hour level

I WANT ONE!!!!!
