dont think the "kits" with the voltmeter, and custom brackets are available in the states yet. ive send like 4 kits to the states so far, and 2 custom dashboards for ppl that already owned the speedo itself, but didnt like the koso dash.

thats the last one i sent over to california, posted a short vid of it starting up.
the price (excluding shipping) is:
koso RX2N/RX2N + custom bracket + voltmeter) = $410
koso RX2N/RX2N + custom bracket) = $350
this price is including a 15% mark up, more than half of which gets gobbled up by PayPal...
one person wanted the voltmeter, while the other 2 didnt want it, when i bought these three during a GB.
