I was also interested in doing scrypt mining and came across an english company called Alpha Technology (http://www.alpha-t.net) that has a Viper Scrypt Miner that is supposed to hash at 5Mh/s. They have taken preorders and have sold out. I don't know anything about the credibility of the company and missed out on the pre-orders, but it should be interesting to keep an eye out on other bitcointalk members who did participate in the pre-orders to see what their experiences are when the miners start shipping this spring.
