Want advice really on any cheap ones jug for general use really ont car. 

I've seen the cheap air ones on eBay but are these any good? I can have air or 240v and really looking to pay very little as it won't get that much use in fairness. 

Cheers all. 

Unless your compressor has a decent air output I'd opt for an electric one.

Can get a steady/constant 6 bar
