Kids recently bought me a Ryobi cordless for £99 .Which is a doddle to go around each wheel, as it also has a push-on connector rather than screw-on, plus it's massively quicker at inflating. Two minute job for 4 tyres rather than 10 minutes.
Half of the cost, is for the battery a bare tool without battery much cheaper), so if you already have cordless tools I'd look for one that uses the brand/battery you already have.
