New Prius owner from San Francisco

Hey guys!

I've wanted a Prius for a looong time, and as of last week, I finally bought a 2012 Prius Three!
I am loving the car so far. THE 3 SKS FEATURE!!!! It's always a little game with the HSI and trying to stay in the low-mid eco area. I've been browsing the forum, but still have a lot to learn about using the Prius! I appreciate any tips you can give me here

One important questions I have so far... Should I buy an unlock/reflash (pre-owned) keyfob from ebay and have a locksmith reprogram it? That's ~$90 + $50 to program, compared to $350+ at dealership or $225 at Art's Automotive in Berkeley. I've read few threads about buying "new" keyfob on ebay and doing it this way. I can't find any "New" one on ebay. My friend is strongly against doing it this way since it may not work and can run into complication.
