Omega PH Meter?

[panamamike]

I have diligently been looking at PH Meters and want something I can use to test cheeses with that will be high enough quality but not to pricey.
I have a Hanna hi98127 that I can't get batteries for where I live in Panama. I will have my wife pick some up when she visits the U.S. in a month.
That still doesn't solve the problem of checking the cheese itself. Was looking at the Omega phh222 and a Alpha phe2385 puncture tip electrode.
The electrode is fairly inexpensive at $ 106.00. It also uses a 9V battery. Has anyone had experience with Omega products?
I would love to here any comments you have about this product line.
