Well I got it for £160 so around £80-£100 less than new and it looks in good nick.
Time will tell how I get on with it I guess. Thanks All for the insight and advice.
In reply to some of the comments you've made PB, I don't think I've ever freaked out about differences in grate v's dome temp as i've never measured the difference!! ;)
Tool kit now amounts to an ikamand, a TP-20 and a Joetisserie, (which I love!). Gadget wise I suspect that list won't grow any further. I like the Doejoe but honestly it's way to much money and cooking pizza using Mr. Setzlers set up of raising the stone above the deflector plates by an inch or so works very well indeed. :)
