Snap-on 3/8" drive kit (ratchet, battery, charger) is $421. This ratchet is rated at 40 ft lb of torque. IMO that's outrageous on price. years ago I had bought my first 14.4v piece. It was a used screw gun that someone had traded in to buy the new one. It was a cheap deal so I bought it. After about a year I decided that I used it so much I traded it back in to get the new one (the new one was a two speed variable speed with an adjustable clutch and led lights) I can't remember what the price was but it was salty. This is a tool I use pretty much every day at work. A friend of mine at another shop told me the flashlight that works with the same battery was absolutely amazing so I bought one. Just the bare tool as I already had two batteries. I have since added a couple more things in this format. I bought the high speed polisher for home. I hesitated for the longest time on the ratchet but eventually bought the bare tool as I now had 4 batteries for 3 tools and this would make it 4 batteries with 4 tools. The stuff all works great for me and the battery life in this format is one of the best I have had on battery powered stuff. I have a Snap-on guy come once a week and when I get these things I just put it on my truck account with him. I pay him $20/week every week. My balance goes up and down but I never let it get high and I only go thru him at no interest.
My ratchet is 1/4" drive and I can use an adaptor if I use 3/8" drive sockets. The thing is NOT a power house. In many instances I break stuff loose with a manual ratchet and use the battery for running things in and out. If there is room for it I used my Mac battery impact in 3/8" drive for pulling bolts out of stuff. it just depends. I have a Snap-on air ratchet in 1/4" drive. it is pretty small too but I find that it is fairly even in bolt breaking loose power as the battery one. I don't use either of them very much. if I was working in a situation where I was doing a lot of higher torque required stuff where I needed fast and power I would most likely get an air 3/8" ratchet that had some serious beef on power but I am not in that position right now.
So for me the entire 14.4 platform from Snap-on works but if someone was going to just buy the ratchet kit I would say it's over priced and not really any better than the other choices listed here.
Another example of outrageous? 17 pc 3/8" metric starter kit. Deep sockets from 8mm to 19mm in deep. Two extensions, a spark plug socket and a universal joint (chrome one, that I would NEVER use) and a little bit longer version ratchet. $570.00 IMO that is just crazy stupid.
