I`m afraid that I can`t help much - I`m not into commercial hi-fi products, more into DIY "world".
There`re some good (and not too expensive) MC -trafo solutions, for example, Menno van der Veen`s MC-10:http://www.mennovanderveen.nl

Or LL9206 from Lundahl:

Of course, for step-up to work you must have a MM RIAA phono input on your amp - if not, separate MC in - line out preamp is in order...
