Cheap MAF's? A reliable alternative?

[fmj]

Hi guys, anybody with a 99-00 Impreza will no doubt have changed their MAF for the sum of about £90-£100 from Subaru. I know you can save a couple of quid buying genuine Subaru parts from various other companies like import car parts etc.

But has anybody tried these?

I appreciate that is not the correct model but the seller does list the right one. It appears to be a Nissan MAF of the same design. Anybody tried it? They are half the price!
