This is something that I find a bit unjust. Mühle razors for us Euros cost only 32€ - I initially got interested in the R89 because it seemed like a cheap alternative to Merkur HD which I was about to purchase at first.
The pricing difference can be seen at Mühle's own web shop ( http://www.muehle-shaving.com/shop/ ). If you switch the country from USA + Canada to Germany/All other countries, you get around $20 drop in price for the safety razors.
Best prices I can find on Muhle for Americans if you don't mind waiting on shipping from the UK. Haven't purchased from them but the shaving world seems to trust this site.
R89 = ~$37 shipped
R89 Grande = ~$50 shipped
Sounds like a deal to me! Just as cheap as the Edwin Jaggers.
