Since my old footpump fell to pieces, I've been using the air line at
the local petrol station. But when it's out of action (or for
wheelbarrow / sack barrow tyres), it would be useful to have a new
footpump at home.

I've looked at Screwfix / Halfrauds / Argos and even the more
expensive Michelin-branded ones seem to have mixed reviews.

I saw a cheap, halfway decent looking one last week at Aldi ---
reasonably constructed but the gauge was graduated in 15 psi intervals
which I guess makes it accurate to the nearest 7 psi and not much use
for a typical 30 psi tyre.

Is there such a thing as a reasonably constructed footpump with
accurate pressure gauge or is it a case of using the air line at the
garage?
