Edit: I also noticed that Brian's SS has a Becker Mexico, which is a fabulous unit and really should be standard...
As you may know, the Mexico ceased production when Becker went into administration. The price of them on the secondary market is shocking. I recently saw one for £4,500.00
The factory did stock them for awhile and it is a shame they are no longer in production as it is a style that is well suited to the Aero line.
