"cheap" (or reasonable) z/OS Account with CICS, MQ and DB2?

Hi,

I may want to switch from been a Java/JEE guy to Mainframe COBOL guy but need a good place to practice with the “real” stuff: CICS, MQ and DB2.

Someone knows a “cheap” (or reasonable priced) hosted z/OS in which I can have those features?

Regards!

Hi Maintec is a very good option.
