No one else is out there. So far only Bitmain and Canaan are shipping miners and looks like it will be that way for along time.
BitFury does have chips primarily for their own use but are willing to sell them to makers IF you have around $1-million to plunk down for their minimum order req. So far only one company has shown a miner using BF chips and that is all -- A miner and no mention of actually producing/selling them (it?)
Sidehack isn't exactly a company (:p) but he is planning on creating a series of bitfury based miners which could possibly be worth looking at. It'll take some time for em to be released, though, but there's supposedly going to be a blade based design which you can replace S3/5/1 blades with.
