In the May 2002 article A Guide to Using Calcium Reactors you mentioned the problems many have with needlevalves. My experience has been similar, those I have purchased and tried have not offered precise control. Do you have any recommendations for a high quality needlevalve?

I have used needlevalves from RS Components in the past. An easier source for people in the US maybe to follow Sanjay Joshi's recommendations in this DIY calcium reactor article under the heading 'CO2 Needle Valve' :

Thanks, I just landed a $150 Nupro 316 SS-4MG Stainless Needle Valve for $28 on e-bay! ;)
