Very well said. I'm leaning away from Snap-On only because I can see this being one of the rare instances where warranty could be a problem. A couple guys I work with have busted long ratchets (one a Snap-On). Our SO driver *****! I haven't seen him on 2nd shift in 6 weeks.
Not sure how one breaks a Snap On ratchet. Head is good for over 700 pounds. So the limit load is 350lbs applied at the handle. If you need a cheater bar, then obviously an expensive ratchet flex head isn't the right tool for the job. Use a breaker for that. I could see guys doing something to break a 1/4" drive ratchets, maybe even 3/8". But you have to be going out of your way to break a 1/2" drive ratchet.
For me, and just spring boarding off Mr Jason's comment, my longest ratchet excluding the SHLF80 is a 13.75" FHDLF80 (not sure if that's the right number, but it's my long HH 3/8" flex). So I reach for the SHLF80 for lugs, some suspension stuff, sometimes brake bolts I can't get a gun on.
To be honest, I use the gun for most 1/2" drive stuff. Only time I get out a ratchet is when I can't get the gun in. And I only have 2, 1/2" ratchets- the SKF80 (stubby flex) and the long handle flex.
In terms of warranty, I believe the drive or ratchet will fail before any other part (assuming the flex pin is torqued correctly). Free replacement under warranty or $10 rebuild kit worst case scenario. Also, if you somehow break the head, you can interchange it with any other 1/2" dual 80 flex head. It may also be possible to assemble a franken ratchet out of a breaker and a flex head. Could be cheaper that way.
The SHLF80 is $215 new, but can be had for a little over 1/2 that second hand. I would expect to pay $130 or so. I would compare that to the cost of a new one from someone else.
One more thing- Everybody here seems to be gaga over these super high torque battery impact guns. Some of these guns feel like they are twice as heavy as air models. I have the Bosch IWHT- it's pretty heavy and unwieldy and by far not the largest or heaviest. So the inconvenience of the airline is now replaced by the inconvenience of manuevering these bricks up over our heads into some small area. In my mind, it makes these ratchets all the more attractive.
So- get the one you like most because if you are like me, you may find yourself using it more than you thought you would. EverytimeIi pick up my big Snap On, I'm glad I got it. I even like the soft grip (tho I wouldn't want it on any other ratchet).
