You don't usually need the added torque of the IR, and you definitely don't need a tool that works you harder. The lighter weight makes work faster and easier, and the CP is also quieter by around half. I've had mine for over 10 years. I wouldn't have any of the $20-specials out there either. They look like tools, but they're really just toys. New guys in the shop would invariably chuck them ASAP once they had the $$ for a real wrench. The only "normal" automotive job I've seen the CP struggle with is the big CV joint nuts on Hondas ... most everything else in my experience was faster and easier. There are easy rebuild kits (that's how my Dad's is still in service after 30 years) that will make sure your CP734 is going strong indefinitely. I think he's put new vanes in his three times now ... The light weight, industrial grade quality and overall performance make this my choice, and believe me, when I worked as a mechanic, I had plenty of tools to choose from. This is the impact I kept. Remember to put a drop or two of light air tool oil in the air inlet each time you use it, and I know for a fact it can last you a lifetime.
I was surprised to find that CP has not yet moved production to China. Mine was made in Japan in 2010, with excellent fit and finish.
This is undoubtedly the smoothest and strongest 1/2" impact wrench you'll find for $100. At 425 ft-lb, it will handle all but the worst stuck fasteners. Mine easily spun out a crank balancer bolt that my 40 year old Craftsman couldn't budge.
The IR231 may be slightly stronger, but it's also more expensive, louder, and vibrates more.
The ratio of power/air use is probably the best of the lot, so if you're working with a smaller/slower compressor, this wrench is an excellent choice. This wrench isn't as powerful as some, but it's got plenty of power for most projects involving cars and light trucks, and it's less likely to do real damage by over-tightening; a powerful wrench can strip a nut, pull out a stud or twist off the head of a bolt in the blink of an eye. This is less likely to do that.
My only complaint is that the owner's manual advises checking the clutch oil every few months, but there are no instructions as to how to do this. Professional users may know such things, but as a home mechanic, I'd appreciate having this information included in the instruction manual. Note that the manual advises injecting a couple of drops of Chicago Pneumatic CA000046 Protecto-Lube Air Tool Oil- 20 oz into the air intake before each use.
Edit: I recently used this wrench to remove a heavy 7-lug wheel off a large horse trailer. I also used it to remove the big-8-lug wheels from my daughter's F-250 diesel pickup. I easily handled both jobs.
