This seems to be good barometer http://davidbray.org/onewire/baro2030.html
But you have to make your own board(it's fairly easy with laser printer  
and an iron) and the sensor MPX4115 is a little bit expensive if you buy  
only one.
On the other hand Hobby Boards ship to Europe for a reasonable price. I  
think that they also have 1-wire counter DS2423 which is out of production.

I'm currently modifying this schematics to use MPXH6115A6U (you can get  
samples for $6 from Freesacle).
I hope it's a good replacement for MPX4115 so I just have to use the  
schematics and only design a new board(I'm trying to fit it in a smaller  
box. I can send You the schematics+board once I finish.
