He he that's just typical isn't it Ian
I mentioned Amplitube 3 in particular because the basic set-up is completely
free, and I reckon even the free stuff they put together in the bundle is much nicer than the LE version of GRig3. The only way it will cost you anything is if, at some stage, you decide to purchase any extra gear.
Plus, as I mentioned to Tedd in the thread I linked to, once you've registered with them, you can sign up to receive e-mail notifications from them and, occasionally, these newsletters include exclusive links to free gear (i.e. stuff that they normally charge for) for subscribers. I picked up a very nice Fender Dual-Showman model for nothing just a few weeks ago.
