I think Michaelbsc makes an interesting point referring to multiple meters. If there's something actually wrong with your meter then get it fixed by all means. But, if you only have the one meter and you think the calibration is a little wayward, as long as it's consistent it probably doesn't matter. If your exposure/development regime already works and is internally consistent, readings that differ from the standard are already compensated for within the system itself. It's only when you come to compare the readings from your meter to another meter that any problems will arise.
If you've already got an exposure/development regime that works, having your meter calibrated (if it is inaccurate) will throw your current system out and you'll have to start calibrating your film speeds etc all over again.
Similarly, if you're using a mechanical camera, it's also unlikely that all the shutter speeds and apertures will be consistently accurate. Being accurate against the standard might be useful, say if you have to work with other professionals, but only in certain circumstances. It doesn't surprise me that the place to get meters calibrated is on Hollywood Boulevard, Los Angeles - if there's one place in the world where people need standardised meters, it's Hollywood. Imagine the problems if two guys where working on the same film from different meters a couple of stops apart!
Even if you want to use the Zone System, it doesn't really matter if your meter is a bit off. If I recall correctly, it was one of the main considerations of AA's system that it was originally designed as a 'closed system', using one meter one camera and one enlarger, thus ironing out any irregularities. It's more important that you know how to take readings properly. In the past, when most photographers were using Weston meters, and even battery powered Gossens, it was quite common to find that the needle was way off zero or, in the case of the Westons, they weren't being held at the correct angle ; meaning that all the readings were 'off', but consistently off., so it didn't matter.
So, unless I knew my meter was actually faulty, I'd save the money for getting my meter recalibrated and buy more film.
