Check www.labx.com

The problem is you don't just need a pH meter. For normal lab use, you'll need:

pH meter, compatible pH electrode, pH buffers for calibration, and electrode fill solution.

Finding any one of these on labx or ebay is trivial; finding everything is a chore. I am looking through the Fisher Scientific catalog now, and I see one promising new pH meter:

The Corning Chekmite pH tester. This might be a good choice (it's a little handheld unit). $60CAD is catalog price. It states: pH 0-14, resoltion 0.01, accuracy +/- 0.2 units. It can be calibrated with normal pH 4, 7, and 10 buffers. Corning part #475660. Replacement electrodes are $31CAD, but provided that you are following storage directions it shouldnt be an issue. Call and ask; they can probably throw in any fill/storage solution for the electrode and the buffer samples at no charge.

I have used Corning semimicro electrodes for years (the fast response ones) and like their products quite well.
