The Clarke ones from Machine Mart might be worth a look if you don't want to spend a lot.
Ryobi R18IW3-0 ONE+ 3-Speed Impact Wrench 300lbs torque can pick one up without the batter for around £100 and u can get different size batteries
the 4.0AH is around the £75 mark £5AH £100
haven't personally got one myself, but used Ryobi tools for years and good quality and decent price point
I've got this one and it's great. Managed to get the body for £80 and as I already have another couple of Ryobi tools, it meant I could stay with one type of battery. I did get an extra 2.5Ah Li-ion battery for £35 from Amazon which was a really good price. It really feels like a quality bit of kit and I'm very happy with it indeed. It's got an amazing amount of power behind it also and it's only ever struggled to undo things which were *exceptionally* tight and rusted. On the whole, rusted bolts and nuts are easily defeated by this. Last weekend I undid suspension bolts on a 15 year old, 120k mile car which has never had them removed since factory and it did so without breaking a sweat.
The other offerings from Makita, Milwaukee and Hitachi are also great but they are *so* much more expensive and I'd only consider them if I was a professional mechanic using them all day every day.
I was just going to reply asking if anyone had any real world experience of the Ryobi tools as i was looking at them yesterday as they look like a good middle ground for the amateur mechanic. I really like the idea of the whole battery sharing thing as i need a new drill anyway so it might be a good excuse!
For my usage of maybe needing it once every few months to do a job on one of my cars there's no way i could justify £500 for one tool, i'd rather spend the difference on a few track days!
Yeah I'm in the same mindset. Just over £100 for the gun on Amazon. But over another £100 for a charger and battery.
But then I do need a cordless SDS drill as well, not sure if I can get a Ryobi one.
What about the Dewalt DCF899.
1625Nm of breakaway torque, with 950nm of sustained torque, can be had for £150 body only.
