In general if you want a combination of reasonable accuracy and
reliability, you need to opt for a higher price station as found in
the Davis range.

But the One-Wire concept always seems quite interesting and fairly
cheap and lets you expand the system in easy stages. We don't sell
these ourselves, but you'll find some details at:

The sensors interface directly with the PC and so the PC display (or a
PC-managed web page) is the only way of viewing the data, ie there's
no separate weather station console. It's also cabled only AFAIK, ie
no wireless option, but it is inexpensive at least unless you add lots
of optional sensors.
