[Highland Park] Need help selecting electric supplier

Hi all, Looking for help, as usual. I'm in the process of looking at the different suppliers of electricity in our area and am wondering whether anyone has had experience with North American Power? They seem to be the cheaper one of only two suppliers that offer some kind of green options. Would appreciate any kind of feedback on this. All of the suppliers seem to be cheaper than Duquesne Light, but are there any pros or cons to sticking with Duquesne Light? Thanks, Claudette For anyone who wants to check out the different rates, a chart can be found at _http://www.papowerswitch.com/shop-for-electricity/shop-for-your-home/by-dist...
