Does anyone know where the best place is to purchase parts for Ultimaker. 2. I need an upgrade kit and trying to find a vendor that I can purchase parts from.
It is easier to suggest a reseller if we know where you are from 
After looking at your profile, i can see that you are in the USA, where i would suggest to get in touch with the great people at FBRC8 https://fbrc8.com/
Thank you Erik. I will take a look. We are from NJ.
