Thanks Ron. If I can ever get someone to turn up to give me a demo I'll more than likely buy one! Someone should've come to see me two days ago but never showed up. No phone call, nothing.

I'm looking at buying the 4425a (should've had a demo today but he was a no-show) because I don't think I can do without one any longer. I've looked at loads of Pico videos on You Tube etc. and to be honest it's scaring the bejeezus out of me! Please tell me I'm doing the right thing!!
