im looking for one. im about to make the switch to hydro and i figure i should get these items. i however cannot afford $200 for them. ive seen threads around where people mentioning they got one here or there. im going to setup a pretty basic flood/drain for flowering and drip for clones/mothers. any recomendations?

Google HANNA PH METER...They have some pretty affordable ones I think.
Might have to buy some calibration solution seperately though.

if you want a ppm/ph meter and don't want to spend too much, go with the milwaukee sm802. Make sure you keep the probe clean and you won't have to calibrate it for a yr(my hydro guy said so) if its dirty brush it with a toothbrush. There was one on ebay for 150, i brought mines for 200.
