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?

Looks OK although they don't offer a price:-)
It looks very like one I saw in my local motor factor. The picture on
the box showed a beefy diecast valve head but on opening the box it had
been cost reduce replaced by a weedy plastic one with a tiny plastic
spigot connecting to the hose. After having one of those break off in my
hand (with a full flat, mid winter, snow on ground and -10degs) I've
searched fruitlessly for a pump with a metal head and none I've looked
at, regardless of cost, appears to have one.
On accuracy, I've always assumed the built in gauges to be crap so
marginally over inflate then check/adjust with a good hand held sliding
pressure gauge. The one I use is a low displacement one originally
intended for measuring air pressure in motorcycle forks and has a slim
plastic piston that has a better than average 2mm or so per psi
division.
