Thanks for further contributions. Just to let y'all know what happened with me...
After reading what has been said here and speaking further to the guy at the retail place I'd found aftermy post here I allowed myself to be convinced that, given the 'free' wheelkit and blade pack deal on the BS350S already offered, I was unlikely to do better at a show. So I succumbed to immediate temptation and told them to bung one in the boot, which they did (three chaps to lift the main box).
Getting it out of the boot again and down into my cellar by myself was a bit more diffcult of course, but doable!
I'd anticipated a struggle getting the stand/wheelkit together, but in the event it was pretty easy - the instructions were actually written by a native English speaker I think, so none of the 'offer the slidig bit to the aft trimmel' one sometimes gets. The diagrams and parts list obviously pertained to a slightly different variant of the machine I had, but nowt common sense couldn't sort out.
Took me the best part of an afternoon to set it up using the DVD guide supplied (which again related to a slightly different variant), but first test cut trying to rip a 15mm slice off a piece of 3x2 redwood yielded a slab 15.06 +/- 0.07 along a 500mm length which made me happy, being my first attempt on a bandsaw. Maybe I fluked it! I wasn't expecting that sort of accuracy.
I've got a number of minor gripes about the way the machine's built (why do you need three Allen keys to change a blade? What's that bit of plastic obscuring the bottom guides there for?) but that's for more research or another thread.
I saved 40 quid on delivery anyway, which could possibly go on a set of instructional DVD's if such a thing can be had...
Regards, Rob.
