pH and Temperature Probe Recommendations

I'm planning on getting an AquaController II or other similar controller
and I was wondering if anybody had any recommendations for good brands
of pH and temperature probes and any good place to buy them from. I'd
like to get probes that will last a few years before they need to be
replaced so I'm willing to pay a bit more for quality, though I would
like to stay below a couple hundred dollars per probe if that is
possible.

Thanks for any recommendations.
