I have the WS3000 and it's fantastic, as long as you don't expect it to be what it's not.
What it is, is a fantastically easy to use, very very quick way of sharpening, retuning or simply honing bench chisels and other blades up to about 2 inches across. It's also great for freehand sharpening etc of shaped blades like carving chisels and gouges when you use the slotted wheel that allows you to see through the grinding surface, to watch the edge of your tool being shaped (a black marker makes this beautifully easy and accurate). Freehand sharpening of other blades on the normal abrasive disks is great, if you are into freehand, but I find personally I need the optional rest and a jig.
What it's not is a perfect solution straight out the box for every type of sharpening. If you have enormously wide plane blades, you'd struggle without a jig, if even that was possible. Knives come up with a gorgeous edge, but that's only using the optional belt drive for knives and long blades (if you have one, let me know if you want a cheap source of micromesh belts for it - I found them at less than £2 each)
The tool rest that is an optional add on takes it to the next level, it's "expensive" at £35, and last time I looked Rutlands managed to miss it from their online catalogue, but it's comprehensively compatible with the Tormek, Jet or (I think) Record Power jigs, and these make it a great solution for turning tools too. Without the rest and jigs, I found it hard to freehand turning tools, especially since you usually work down onto the flat sharpening surface, or else have a small upward undersurface to work on.
I bought the Tormek set, and even though I'm a turning rookie, with some patience, plenty Tea and bright lighting in the workshop, I managed to take my first bowl gouge from a horrible to use stock grind, to a beautifully even and shiny sharp Irish grind inside about an hour. Yes, that's an age and a half, but considering I was doing it the very first time, and got a damn near perfect result, while shortening my gouge by less than 1mm, I think it was a great result
A note though, it's worth buying an extra glass disk with it, as you never seem to have enough of those to go with the grits, and you really, really don't want to be peeling off abrasive that's not thoroughly worn out, as you won't get it back on again. I bought two extra glass disks, and spray mounted leather onto one side of one, to use with flexcut gold wax as a strop. It saves me heaps on buying the expensive 6000 grit micromesh adhesive disks.
I know this is pretty glowing and fanboyish about the system, but I really do think it's underrated. Most criticism of it that I've seen comes from those who didn't want to change the way they worked to a different system, or got fixated on the things that it doesn't do well (all the things I found it needed the jigs for, or wide plane blades).
If you're thinking of getting one, take these things into account first, and if you want to use it for the things that it *is* good at, you'll love it.
