We use Ingersol Rand W360-2L impact guns at work which are pretty powerful pieces of kit. I can crack off bolts that have been torqued up to 400Nm no problem but for the big stuff I have to fall back onto the 1" drive air gun that can go up to 750Nm.
Might be a bit out of your budget though, they go for around £450-£500
