I just replaced my Specialized Prospero after 2-1/2 years of use. Not due to the time in use, I cracked it in a crash on Jan 2. Glad that I had it on when my head hit the pavement from looking at the scrape marks, and the fact it is cracked all the way through on the right front quadrant. Picked up a new Specialized, the Echelon model, feels good in use, no complaints about it so far.
It seems that every issue of a road cycling magazine has a group of new helmets they are reviewing. Right now they are specializing the helmets, with aero, light weight, vent or no vent, built in lights for commuters, different suspension systems. Bell is coming back after a while as a low end brand, and most of the different clothing and bicycle makers have a helmet line. Lots to choose from now, Deege, best of luck on your decision.
