Angle Grinder - Wattage, Button/Trigger, and Recommendations?

[lostinthelight]

I've used the 115mm Makita cordless, its a tidy grinder, nice and light.... but has a terrible on/off switch... especially when its covered in dust!

I blow mine out every time I use it which does help. There are or maybe were, two types of switch on these grinders but went for the paddle that doesn't lock in the on position which I think is safer
