If you really want to nerd out, you can mission plan.
Haven't noticed any trouble with my eTrex 30 recently - still picks up a signal within 30 seconds of turning on, even in my crowded residential compound surrounded by 12 storey buildings. I think the fact that my receiver picks up GLONASS as well as GPS helps acquisition time, though.
