I'd still go with the LM3909.  It does wonderful things to battery life.
I used to build display model aircraft.  The first was a B52 (yep, da BUFF)
that used 555's to run the strobes.  A 9v battery lasted about 2 hours.  
The last one was a large Tomcat - with 2 seperate beacons, INCANDESCENT 
strobes (they look GREAT!), cockpit lighting - the works.  Two D cells in 
the tailpipes lasted over a year (using LM3909's and CMOS logic chips).

One idea (not yet implemented) was to make _WORKING_ _SCALE_ radar display
screens!  Can anybody guess how?
