I want to install a power commander on my cbr 929 2001 and I was wondering were was the best place to buy it from price wise?

 

I bought a older serial port style for my 954 off of eBay for $50 and its works as it should, just had to buy a serial to usb port for my computer. It loads and holds maps as it should. After I get back home I'm getting a custom map. Be careful if you buy off of eBay though, used stuff sometime you get screwed on. For used another place to check is craigslist maybe find you around you and check to make sure it works before you buy it.
If you want a new one you could also check out ebay or bikebandit.

 

I've seen several on craigslist.
