Eric at EHS will hook you up with a deal usually if you tell him you are from the site and trust me EVERYTHING on that site can be purchased somewhere else for cheaper.
I think Jokersracing is just a middle man marking the products up.
Examples to help you:
Go to PRM for any of that PRM stuff for cheaper
Pro Armor go to ATVGalaxy.com for cheaper (quality still sucks on most of Pro Armor's stuff though)
That EFI controller from EHS they are selling is $100 cheaper through EHS!!
The hotcams are cheaper on Ebay
The only thing they have that I havent seen before is the NOS. Its great that they are a sponsor and all but I am all about getting the best prices and they are not all about having the best prices!
