My research showed the Faro ones all had terrible reviews so I just went with the cheapest, a company called LC rent via the Zest car rental site. £180 for the week including the transponder. A late evening pick up from the shed in the car park wasn’t a nice start to the holiday but reasonably efficient.
Was a very beaten up Corsa automatic that sounded a bit ropy but ran ok. Our flight was crazy early and the out of hours drop off consisted of leaving it in the car park with the keys in the glovebox. Took videos of everything but never heard anything from them again.
I would maybe pay a bit extra next time to pick up from the airport desks, and hopefully a newer car, but not loads more.
Definitely get excess insurance, saves loads of money and they do pay out even against total crooks like the Alicante OK Mobility lot.
