O2 Simluators, looking for advice!

[RDKamikaze]

Ok everyone, I'm looking for advice on O2 simulators. I'm a froogle buyer, so I'm not fond of spending lots of money. Does anyone know where to find a cheap O2 simulator/does anyone have one they'd sell me? If you know where I can get one pretty cheap, that would be great help!

Also, I found a few sites with simulators, but I'm not sure if they'll work (noob to this stuff). Here's the links, and let me know if they'll work/are good enough, thanks!

How to make one:

Also, what's the difference between mechanical and electric o2 simulators?

i you want cheap, just go and buy those spark plug anti foulers for 4 dollars.

i used o2sensorsimulator and it didnt work well. i think toyota's sensor voltage is very different than others.

what about www/o2simulator.com i20solara02i told me to get that one. He's the one I'm getting the headers and intake on, so I'll probably just get that one if people have tried it and it works.

Anyone have experience with that one? Let me know, thanks!
