As others have already pointed out, adding tools and techs to your CV is a _good_ thing. It shows the Suits that you are not just a (fill in the blank); you do not want to get pigeon-holed as a one-trick pony.

The real question here is your statement "The job will probably involve more money, but relocating to a place that I dont really want to be." You need to analyze why you are thinking this.

Is it because the new location has physical defects? (I have turned down more than one job because it would entail living in the Los Angeles Air basin; and I wouldn't take a contract in either Bagdhad or Jerusalem right now, either.) Are there social defects? (The new city is too big/small? Will my Wife/SO/LTR be willing to relocate? What is the cost of living like in the New Location? Can I afford to move?)

You need to analyze your hesitation factors, because no matter how good the job is, if you are not happy with where you are living, you won't be happy with the job.

This is a long way round to say 'it depends' Adding a new tool set is a goodness. Living where you don't want to isn't. Also consider, you are _not_ stuck in any job. You can always take what you have learned and apply it elsewhere. Having more than one tool set on your CV makes that move immensely more possible. (I got my current gig because the hiring-manager looked at my job history and determined that I can learn almost anything. (I have been a Mainframe COBOL Developer, a Systems Programmer (IBM and Hitachi main frames), an UNIX SysAdmin, a Mail Engineer, a Directory Developer, and a Perl/COBOL/FORTRAN/C/etc hacker during the course of the last thirty years.))

Think about your options. Consider why you feel the way you do about the new job. And also consider your feeling about the current job, are there things that will increase your satisfaction level? How likely are they to happen?) Once you have worked through these equations you will have a better feeling about your final decision.
