PPM meter

Well, wait for a few others to chime in. I've tried the analog $6 ones and got no luck. That, and I have no prob on spending $$ on tools.

I know what you re saying man, but I dont have 70-100 $ to buy a VERY good PPM meter... thats why I asked if anyone knows anything about this cheap shit from ebay
 
It might work, but more than likely will stop functioning after a short period of time and you will buy another cheap ass one, until you have purchased $200 worth of shit before realizing you could have just gotten one good one and saved money in the long run.

This is a very nice instrument http://www.hannainst.com/usa/prods2.cfm?id=005002&ProdCode=HI%209813-6 and is what I currently use, and has worked well for years. A bit spendy at about $230, you can get it cheaper on E-Bay im sure.
