I bought low angle jack plane from Lie Nielsen in USA via their web page.
It arrived via airmail in 4 weeks and I had to pay import duty on it. I believe that these planes are sold somewhere in the UK by someone. I also believe that there is a woodworking fair/show coming up somewhere in the south East in October where their planes will be on display/sale. A Lie Nielsen employee told me this on the telephone while talking to them when I ordering my plane a few months ago.
It is a great plane, but not saying it is the very best, but as I have never used a top quality plane before this one I find it amazing. It is not cheap but when you hold one it feels great, looks great and that alone will make you look after it properly and keep it sharp. It is a joy to use though I have not used it that much as I am building a new workshop at the moment and the tools are in boxes for a few months.

PS: If you are sepnding this kind of money on a hand plane you should check out other brands.
