a panavise can be adjusted some to make it easier or harder to move and buying one has probably been some of the best money i spent with all my tinkering with stuff. i have the normal vice jaws and use it for every thing from airsmithing to electronics to doing honey do's and some.
I also agree flux is wonderful. when i first bought a bottle i had been soldering for years already and ended up asking my self why i did not get it earlier it makes life a lot easier.
