I based my cost on solarblvd.com having lager panels for $150 plus shipping, a eco-worthy 20a MPPT controller for $100 shipped and the cords for $32 shipped. With you living in Ma. you might find a better deal on the shipping. (it was $60 to Denver when I checked)
Honestly 230w is a lot for a low power user. A 120 watt set up would probably suit you fine and not be as hard to manage. I don't have a issue lifting the 50 lb panel up on the truck but there will come a day......Hopefully be then I have it mounted on the roof.
