I'm looking to buy a small air compressor, mainly to blow out the dusty
insides of stuff I'm repairing or maintaining, but it would be great if
it could do other stuff as well, such as inflating car tyres and maybe
some spraying of fence panels.

I don't want to spend a great amount of money on it so I've got it down
to the choice of two - I think :-)

Any thoughts on which to go for between these two on Ebay (I visit both
towns regularly so could pick up in person from either of them):
