Like i mentioned, in our shop we have had so many problems with aftermarket sensors being out of calibration that we have given up on using any of them. If you want to gamble, Bosch is as good as any aftermarket one; give them a try. There is a possibility though that they may not work properly. I would avoid any kind of universal sensor; "universal" translates to "doesn't quite fit anything exactly". If you ahve to solder on electrical plugs you are creating an unknown amount of electrical resistance in the circuit, which usually affects vehicle operation. Oxygen sensors operate on less than 1 volt, so a 1/10 of a volt drop across an electrical connection makes a world of difference.
Something you may want to consider is seeing if any local salvage yard has the sensors you need available used off of a low mileage wrecked vehicle... that might be one way to save a lot of $$$ if you can find a good one.
