I have a budget for around £100 so I'm looking at the lower end of the scale but that market is like a minefield and I'm still toying with either electric or battery. This does not mean that I wont go and buy a 2nd hand Snap on one if one came up at the right price. I am a bit of an impulse buyer at times even if that means getting into debt. Sometimes. Lack of sense overrules brain.

I think I may be dreaming a bit here. I shall have an argument with myself now

Are the electric ones really powerful enough to remove, say, 150lb ft with ease. Is it worth me considering a battery operated one or should I forget about that idea straight away and go for the electric.
I have narrowed down my search and would like your opinions on the following. Has anyone had experience with these. Is there one anyone could recommend.
My favourite so far as the price is right and it gets good reviews on the net is the Clarke electric. It also comes with a few impact sockets which saves me buying them separate at this stage. My gut feeling it telling me this is the one to get.

They also do a cordless version

The following boasts about the RPM but has a lower Max Torque.
Which is more important RPM, Max Torque or the Impact Rate.

This one seems interesting, looking at the specs and may be better than the Clarke. It's a German company so may even be made there. Don't know but the listing implies it by mentioning quality.

Read some bad reviews on the Sealey battery one which surprised me considering the cost. It apparently does not have the real world power they say it has.

Maybe worth considering for the price and it comes with two batteries and a nice selection if sockets.

The beast. A little overkill me thinks

First tough bolt I will be undoing is the flywheel bolt and this is needed for that
