Which Grease Gun??

Gents,

Not sure if this is the right place to ask or not although many a word have been spoken about the best oil cans, so this isn't too far removed!





I need a new grease gun. One for general use, must take the standard 500g (??) cartridges, have an interchangeable nipple end and shouldn't leak when the temperature rises!



Any suggestions?





Thanks

Jon
