Just FYI, you cannot buy a cluster and install it yourself. In 2006, they came out with a security feature, called "marrying", which is a process where you write the serial number of the ECU in the cluster using BUDS or Candoopro. If you don't marry the cluster, the fuel pump will be deactivated and the ski won't start.
Also, OEM replacement clusters sold by BRP for the 2006-2009 are a generic cluster with no programming in them. So you are faced with a very few set of options:
1. Buy a new cluster at a dealer and negotiate for them to include the cost of programming and marrying it to your ski
2. Buy a used cluster, and buy a Candoopro system to marry it to your ski
3. Buy a used cluster, and take it to a dealer or shop with Candoopro and have them marry it for you
4. Buy a new cluster from Candoopro (they sell them preprogrammed) and buy a Candoopro system to marry it to your ski
