Handheld fev1 device

Hi all,

Just a quick question to those who use a handheld device to monitor their own fev1 levels. What device do you use/recommend? (preferable available to buy in uk)

I used to just use the nSpire Piko 1 Hand held Peak flow Meter see here:

Had it for about 3 years but went and dropped it so looking for a new one or something similar, any recommendations? ;-(
