Slime compressor or Repco

Several years ago I bought a Repco 12V for about $140, still going, it's served us well
However, we hardly do a great deal of beach driving.
If we did do a reasonable amount of beach driving, we certainly would pay more for a "better" one.
They tend to run out of puff after a while (overheat & cut out) when pumping up multiple medium to larger sized 4WD tyres from 18lb.

G/day Mick, you can pay lots of $s for ARB etc but for normal intermittant use I reckon the double cylinder clones on ebay are the go, around $100.00.
