ph meters!?? who knew they were so important?

so im in the middle of finding the best ph meter for my needs. they range everywhere from cheapo meter at under $20 all the way up to hundreds for commercial use. for my gheto rig i just need something that works well and not gonna break or need a replacement every year. i was looking at the hannah model on a certain cite ( not to advertise ). its about $33. my homie has the older version of this one. if you know what im talking about cool. if not.. what is the best model ph meter i can buy at a reasonable price.

please let me know quick. im collecting cash to get one. its kinda a rush because my plant is truly starting to suffer.

what do you think... and where can i get it for that price?
