Ph probe meters?

Been looking for a good priced probe metre that is reliable and decently priced.
Been using cheap ebay meters and I want to upgrade to something nice.

Been looking at bluelab guardian and it looks amazing , but is there anything similar that's cheaper or should I buy one of these for 300$

get the guardian if you want a continuous ppm and ph read out at all times if you want a unit that is a little cheaper that is still both. I'd go with the Combo Meter from bluelab a little cheaper and still has a 5 year warranty or t save more what i have in my garden is just the bluelab ph pen and the bluelab ppm trunchen and they rock. the combo meter is bomb as well.. bluelab is my fav.
