Anyone have any experience with universal Lambda sensors?

[Iamzod]

I'm after a pair of Lambda sensors & have noticed "Universal" Types on e-bay that are far cheaper than the OEM ones, less than 1/3rd of the cost.

Anyone have any experience with these things, will I just be throwing cash away or are they just the same in functionality as an OEM part?

It's a 1992 engine with 3 wire sensors btw so nothing modern.

I'm just going to go ahead and try some cheap ones as the car is never going to be a daily driver, i have found the pair as "universal" sensors for £22 whereas Euro Car Parts has the Bosch ones at £185 for the pair.
