I do indeed have the Bosch. Do I need the double-bevel facility? Well I have used it, simply because it's there, but probably, if I'm honest, I <i>could</i> live without it. But why would you want to when the rest of the GCM10SD is so lovely? Big table and fence, all the angle adjustments accessible without grovelling round the back (very useful when it's against a wall), handle angle adjustable to user preference (yeah, I sniggered too. But I use it), all the every day tasks tool-less (but all the tools on board for everything else anyway), quick action work clamp (my only quibble is it's a bit easy to skewer yourself on the upright when snapping home the clamp lever - but I don't honestly see how they'd have got rid of the problem) etc etc. Even the trenching facility isn't hopelessly clunky. It's a great saw and I'm glad I've got it. Just wish Axminster's offer had been around sooner; makes it a flippin' bargain.
Oh, and it's a big sucker - be warned.
