i have and it is totally easy i bought the kit at wal mart...came with a blue hose(w/attachments),and 2 cans of r134a...i think it was less than $20...
its simple all you have to do is screw the can on one end,and attach the other end to the LOW pressure a/c line..it has a little plastic cap on it...it will only fit on the low precssure,it just snaps on...then you puncture the can by turning a bolt and as you loosen that bolt it fills the a/c...
slow process sometimes,just let the can empty all the way,you can tell when its done...the outside of the can will not be cold anymore..you also have to leave the car running with a/c on...
very simple to do,you shouldn't have any problems...
