Vertex Electronic vs PFO Pulse??

If you aren"t scared of doing a little wiring, open up the ballast box (unplug first!) and look inside at the ballast. Get the model number of the ballast and call your local electrical supply contractor, like Nedco, and order a new ballast and capacitor. When you get the replacement, use the same color coding, ie. connect the same colored wires as the old ballast. It may look scary at first, but its pretty simple, connect red to red, yellow to yellow, etc.

I have done this on several occasions in the past. It isn't hard, will save you money and the replacement ballasts are easy to get.
