LF-Ballast parts for 70 watt DIY light
 

Anyone know of a good shop in Vancouver (preferably downtown or close) that selling parts for MH ballasts? Or the MH ballast themselves? Just looking for some parts for a DIY 70watt MH light...simple kind made from a halogen shop light.

Or if you have an extra or old ballast laying around and want to sell, let me know!

Thanks!
