Simon you're spoilt with your tm so comparing yours to the etm is a bit silly yours would suck it up. I was suitably impressed with the etm at 100ft, I used my bane with 2 vac blowers it was quite a hassle.
IMO if you get a tm get one from a supplier you like, also I'd get a big one the engine will not be running it's knackers off.

Shaun,
I've got a Maxx 450d as well as the 875 and while the 875 could suck a bowling ball out of a closet with the door closed, the 450 isn't quite as powerful but very economical and highly reliable. To even contemplate an ETM you have to be certain that you can pull up at every door or driveway and sometimes that just isn't possible, so you have got to run not only hoses to the job but at least two power cables across pavements and grass etc with the obvious safety concerns that go with it.
