Of course there's the
less than $50 MPGuino option for the DIY crowd...
But I've often said to reluctant noobs that if you can't bear the thought of parting with $150 for a new
ScanGauge, you could always use it for a while and re-sell it later to get most of your money back. There's no shortage of people willing to fork over $ for a used one.
Never mind the long term reality that if you're serious about saving fuel, the thing will pay for itself many times over anyway if you use it to hone your driving techniques and learn your vehicle's fuel economy idiosyncrasies.
Anyhow, the proof is in the pudding: the latest eBay auction for a
used SG2 just ended at
$126.52 + $8 S&H =
$134.52 ... for a
used ScanGauge!
A whopping savings of $14.48 over buying new (@ the EM group buy price).
used SGII on eBay (not mine)
I should own stock in the d@#n company...
