Looking for a CO2 Inflator - Recommendations?

After flatting on a group ride monday night and struggling to get the tire re-inflated - someone was kind enough to lend me her CO2 inflator - all I can say is wow - I need to get me one of these…

Anyone have suggestions? - from a search on old posts - the overall recommendation is to get one that takes threaded and non threaded cartridges…

Thanks

I use the non threaded ones all of the time
This one looks like the one I use

You can find the cartridges at a paint ball store, normally 25 for about $12
