I have no interest in SoS but recently had to make the same decision.
Without seeing the actual components you have I can tell you the minimum differences are:
- Technical knowledge and installation manual
- Chris includes Acura Caps that have holes cut out and come with gaskets to keep the water out
- SoS stands behind kit
- Kit includes all the misc hardware you need for the installation (bolts, wire ties, industrial velcro, etc.)
I shop a lot on Ebay and have purchased things that were not that much cheaper then retail. These things inevitably go bad, need a lot more work, and have nobody standing behind them.
If you want to figure this out on your own, risk water getting in the housings, have nobody to call if there is a problem, and make 3 trips to the hardware store to save $150 bucks - then step right up - your DIY HID kit is waiting...
