What is a reasonable price for a vintage Jack plane in good condition? I've been looking at the usual sources for these, and it seems all over the place. It also seems like the Type 11 is "the one to get" but why? Does it make that much of a difference between the various types? I understand the lateral adjustment wasn't present on the earlier types. It seems ridiculous to me that a vintage Bedrock Jack would cost more than a brand new LN, but then again I don't put too much "value" into a tool being vintage.
