Re: [CAD_CAM_EDM_DRO] Re: Motors

BTW, the name of the place is Electronic Surplus, here, in Toronto.
They got lots of capacitors, small mountain of transformers and so on. About
5 years ago I got there a scope for $50 (still works).
For my friend I bought Leintz microscope for $150 - he later resold it for
$2000 US.
List may go on.
The name of the guy who runs it is Sid Lipkowitz, he can be reached at
416-787-1837.
Regards, Alex
