I haven't had mine for too long, but it has become my go-to-flash. I use it for everything, but that might also be because I only got 2x Vivitars and 1x 580EXII.
The Ranger fires when I want it to fire, the lightning output is great, the recharge-time is great(I got the Speed pack) - so no, I don't 'save' it
Don't have any boxes for it yet, but I got the Varistar umbrella which comes with the kit. But it's all bent out of shape, (Tommy Larsen's fault!! ;-P)
I'm mostly using a cheap reflecting umbrella, and one white for shoot-through. Don't do too much portraits and stuff yet, so I haven't put any money into expensive softboxes etc.
For actionsports, I use the standard 45 degree reflector, and the 11" sportsreflector.
