I think my next big purchase will be a dust extractor for

You'll just have to buy many tools so you can save as much money and feel good about it as many times as possible.

You say a "big compressor", but if someone didn't have room/budget for the biggest, what would you say would do the job for most people? i.e. enough to spray one guitar at a time, and run a reasonable selection of tools (mirka sander being an obvious one).

@jonhodgson This is my SIP Airstream AS 3HP 150

I’ve had it maybe 25 years and it’s been good for every air tool I’ve used with it. Air sanders are quite greedy for air so anything less than this size compressor would probably struggle to keep up. Back when I sprayed cars, I could do a full respray using a standard conventional full sized spray gun and this compressor would keep up. If I used an HVLP full sized spray gun for such a task, it may struggle because these types of gun demand more air to work at optimum pressure. I’ve used air ratchets for dismantling and rebuilding car bodywork and if some of it is too smashed in, I’ve used an air nibbler for cutting through panels like I’m opening a tin of baked beans. It will drive a wheel nut gun, although the nuts should always be tightened by hand (insert your own joke here) using a large bar and socket. It’s been a good all round workhorse but I will be upgrading at some point, I certainly wouldn’t be settling for anything less for my needs. It’s better to have a larger compressor that can easily handle things than a smaller one that is being constantly red-lined, putting it under intense strain. 

If you use this spec as a baseline, you can see what is out there and what options there are. There are motors that are straight, motors that are in V format (these are faster than the straight) and motors that are much quieter than a standard one but these are obviously more expensive.

It will take some looking into but I’ll have a look as well.

When I do get a new one, I’m going to house it outside of my workshop, whether that is in another room or in a purpose built cabinet outside the workshop. The airline will come through a hole in the wall where a regulator and water/oil trap will be mounted on the interior wall of the workshop. The main reason for me to have it outside the workshop is so I can use an air fed mask when I’m spraying paint so I’m always breathing clean, fresh air. If the compressor was in the same room as where I am spraying then it would draw in the paint fumes and pump them straight into my air fed mask, that’s no good. 

I hope this rambling has been of some help and I will start looking into the current compressor market to see what is what. 👍

Fun fact, I bought the air compressor Mirka over Christmas and only when it arrived did I notice it was the air compressor version and I don't have a compressor. That's what happens when you have amazon on your phone and too many Christmas beers. Anyway, I sent it back after looking at prices or rather after trying to decipher which compressor I'd need which I couldn't so I gave up and sent it back. I almost mentioned it here but for the embarrassment. 

A quick google of that models is coming in at about 5-600, if you factor in saving of what about 380 on the air comp Mirka alone against the electric it's not that crazy an idea. Thanks @boo all ramblings are really helpful.
