GM Howard,
a problem with projects here is paying the S&H charges on many small
orders to get them to Canada. It would work out cheaper to see if I
couldfind one repairable or intact boatanchor to use for parts or to
repair and get the shipping over in one larger payment. It recently
came up when I was looking to buy something from RF parts and the
minimum charge for S&H on international orders was $20. So if I had to
get a variety of bits from a few different places it starts to get
expensive.
