They did make the MX-450 for their professional line but they have its baby brother the R-50 on the consumer side of it. There is a manual for it here.

The R-50 doesn't have RF and it can't edit macros you just have to redo them. I think the tips on the R-50 are a little more comprehensive. But otherwise they are very similar.
