Which 12v air compressor?

There seems to be that many opinions, and I've searched and not came across any good answers. Which air compressor would others recommend? At the moment I'm looking at the t-max ones, probably the adventurer but they're around £55 and I'm not sure on model numbers. Or I'm looking at the ring rac900 which has a lot of good reviews and it what I'm leaning towards.
Cheers in advance

I use a Ring RAC900 which is perfect. The air pipe is plenty long enough to reach to my caravan tyres when hitched. Comes with its own carry bag and does the job just great.
