I have one of these they work great, but bear in mind that, you need the battery & charger. As far as i know Bunnings are the sole suppliers for Ryobi Tools in OZ
Bunnings have them for $99 don't know if that includes the battery and charger but most of the Ryobi One + 18V stuff usually does, if it doesn't include them any of the other Ryobi One + tools uses the same battery and charger if you happen to have one. I have been thinking about getting one of these units myself Papou not only for the things you suggested but also for adjusting the pressure in the air bag suspension.
Yep $99 for the skin ONLY.
If you don't have at least one battery and a charger, it will cost you about $100 odd or more.
I have quite a few of the tools in the range, and it seems best to buy when they have a package deal going on special, like a drill kit with battery and charger etc.
Seems to be reasonable quality tools over all, but will be expensive to start the collection. They don't sell the smaller tools (like the radios, lights, air compressors etc) in kit form.

That's unfortunate Woofta as it puts the cost up for those who don't have any of the other Ryobi tools but I previously bought a Ryobi One + drill kit which included 2 batteries and a charger.
