MRC Sound Systems

I am trying to decide whether to by an MRC Sound Station 312 or an MRC Synchro Sound Box for Diesels. They both cost about the same so price is not an issue.

Does anyone here have any experience with one or both or these units? Any thoughts on what each unit is best at?

I am currently DC and do not plan to switch to DCC any time in the foreseeable future. Plus, the fact that I am N scale means there is not a whole lot available for me in sound anyway.

Thanks for any help you can provide.
