Looking at getting one for the workshop, any features I should look out for, I would guess that nothing special is required for pumping up tyres, or is it possible that the air flow could be a bit slow on some cheaper models.

Any specific recomendations? Really must be below 100 quid, preferably less or the cost to gain isn’t worth it.

one with a biggish tank, I reckon

(I got one from ALdi years ago, seems fine for the job and was as cheap as you’d expect)

I got a Lidl one and I’m lovin’ it, now I’ve got it to work with a prestaflator.

They only do them from time to time, but there’s a new one on ebay now if you can get to Brum…

Aldi, does the job

There are loads around for <£100. Just look on a Screwfix or similar for them. Check the reviews on those sites as well.

There are a lot of decent compressors around for about £75
