Hi John
I used one of these on my course and was impressed with it
I was going to buy one from place I did course but found a cheaper place online

I have no idea what the company is like but apart from ebay it was the only place I could find. Hopefully others will pop along and tell you a better place.
Don't discount the plasplugs master though - I used one of those too and found it to be excellent, if a bit messy - the briccolina was certainly cleaner for thos must do in doors cuts
