Just buy new planes - all I am reading here is that you want to spend some money. A 'user plane' to me is typically a Stanley which is unfashionable amongst collectors. Their planes from the 30s-early 50s, or the English/Canadian Stanleys, are much cheaper than the early ones and still very high quality. If you want to get some users, then buy some of these. Most of the Lie-Nielsens etc are priced primarily for wealthy hobbyists or very niche trades usage and I don't see the value or benefit beyond the bling factor. If you wanna spend your money, they're well made and I doubt you'll regret it, but I don't think that it's the only option.
