Hey Chrys. I'm sure there are some BOM's available. Check the EZ1290 thread, first page. I'd suggest getting adept at creating your own carts from distributors, like Mouser.
It's a good thing to get to know...even if it takes a week or two to get it together. You'll be glad you did it...even if you make a few mistakes.
Make sure to check lead spacings on components (to match the board), voltage and heat ratings, axial or radial, etc, etc.
