I recently worked with Console5.com to get a capacitor kit for the model 100 and as of today they started selling them. They use high end caps and can save about $4.28 including shipping compared to buying the capacitors from Mouser. On a side note I get nothing out of the kit being sold I only do it to try and help out the community.
