I started with a Edward Jagger 89L, I got mine for $39.75 Canadian so it should be well withing your price rage. They have the same head as the Muhle and a very high quality finish. Don't rule out vintage Gillettes either. You could score a Slim Adjustable, mine was $30 shipped, or a couple of Superspeeds, I got a Rocket, the Canadian/British version of the superspeed and an Aristocrat for $20 at a flea market.
