I guess I'm just a little wary of the learning curve with the HeadBlade.
...it's taken some practice to get the best shave I can. But no more practice than saying use a new remote control for your telly.
I think the learning curve is what's kept me away as well,
I started with a HB and don't think there is a massive learning-curve at all. Follow the basic rule of NO PRESSURE and you'll be fine.
