Alfa 156 MAF replacement

I need to change a MAF sensor on my 156 1.8 TS, and the difference in price on ebay is enormous, so does anyone know if it is a good idea to buy one of the cheaper ones, does anyone have any experience with this???

I had MAF problem also with Alfa 156 1.8 TS. Tried to find replacement MAF sensor on ebay but mechanic advised me not to buy cause they don't last long.

In the end, I bough original one for 260$. :/

In any case thank you for helping me.
