Be sure to get calibration fluids when you get your meters. And pH up or down, whichever you need.

I got my meters off E-bay.

I got both my meters off eBay you can also get your cleaning/calibration/storage fluids there also. I also have a Hanna and could not be happier with it :hubba:
 
you can try sciencecompany.com. they have some pretty cheap meters on there. some for like $15. i havent yet to try any of them but i figure that they cant be any different than any of the more expensive brands.
