Coastie,
I'm new here, but the wife came through for me when we discussed putting together our kit's......she had gone out on some errands, and on her way stopped at several Thrift Stores, (Salvation Army/Goodwill), types.
Next thing I know she's honking the horn, and I'm carrying in a large selection of Tin's in all manner of shapes and sizes! And all for less than a Dollar apiece!
Hope this help's some!

Krell
