Took the plunge and bought all the yeast starter equipment (all $40 bucks of it, but who on this forum isn't thrifty) and holy ball sack did my IPA take off. Put 5 gallons in a 6.5 carboy and I still have blow off. Fermentation started in 3 hours after I pitched my 500ml starter at high krausen. And this was with yeast I had in the fridge from 13 months go. Anyway I'm sold.
