MCSE MAC Administrator????

I am thinking about taking a Macintosh Administration job. I don’t really know if this is a wise move since I am MCSE certified. The person interviewing me said I would not get the chance to use my MCSE except for maybey Networking Essentials. The position is really Desktop support that would lead into Network Administrator. The only problem is the whole network is on MACINTOSH and no Windows machines!I am really anxious to want to take this job since I have been in Helpdesk for a year. I know it would be a added skill, but isn’t it a little off the beat and path of what I should be doing???? If anyone has any experience with this or has any comments on taking this type of position would be appreciated.
