Hey Ken,
I live in London, ON. I have no parts to sell you, but look at "Paul and Sabrina's 144V Open Source Motor Controller" thread. If all goes well, i will be doing the solder work for the beta testers (which could include you). If you buy the parts (under 400 dollars), i will assemble the electronics and you're well on your way to a very cheap and very capable BDC controller.
If you're new to this stuff, you need to spend a couple hundred hours at
DIY Electric Car Forums Site Home,
EV Photo Album: Our Electric Cars on the Web and
www.evdl.org to collect the infinite wisdom of the interweb geekery. Good luck
