Best mastic / caulking tool?

[Alan Ambrose]

I have an old Fugenboy set, but I find the smallest profile is a bit big. Maybe there's better versions / designs anyway these days?

 

Also, I see there are some part-used tube sealer things around - are they any good?

 

Lastly, my cheap old gun hurts my fingers after a while - probably something to do with the sharp edges. Can anyone recommend a good one?
