PH meter - what kind / where?

Sorry if this has been answered but I didn't find it by searching....

What kind of PH meter am I going to want for my hydro set up? I just read test strips aren't really that precise.

Recommendations on where to find one?
Online (link me!)?, ebay? Home Cheapot? Other home/garden store? Pool/spa shop?

Go to ebay and search for "pH meter" there are a variety there, or you can look at BGHydro .com or Google .com

^There are your links.

Blue Labs is considered the best.
Hanna also tops (some do not like, but cant win 'em all)
Milwaukee isn't bad either.

Get one with replaceable probes. They only last a year or so.
