I bought an ex-demo Tiger 2000 about 2 months ago for just under £70 and am very pleased with it. After sharpening some spokeshave & plane blades with the supplied flat blade jig, I then spent nearly twice the cost of the machine on the Tormek Woodturners kit of jigs to go with it - which has been a very good investment (I've still to modify the Tormek narrow leather honing wheels to fit the Tiger - all the other Tormek jigs & parts in the kit work fine - even the Tormek machine cover fits).
I've used a friend's Tormek and although the machine it's better finished & has a few minor features the Tiger doesn't have I don't think this justifies the massive difference in price! The Tormek jigs probably are worth the money as they are well made and I find them very easy to use.
My friend suggested I upgrade the supplied wheel to a Microcrystalline grit type as I am mainly using the machine for HSS bowl gouges & yes, I was wearing groves in the original "soft" wheel - he did the same for his Tormek.
I ordered the new Microcrystalline wheel (just under £60 from Peter Childs) a couple of weeks back before the prices go up like everything seems to be at the moment. I keep the original "softer" wheel for use with flat carbon steel blades - & it's simple enough to swap the wheels when required.
I had no problem trueing & dressing the original wheel with a matrix diamond dresser hand-held on the grinding platform - the new Microcrystalline wheel has not yet required this and shows no signs of wear despite having repeatedly sharpened several bowl gouges.
One tip I would pass on for any wet grinder;
Use Honerite Gold in the water - yes, it is expensive, & yes it colours the water a truely virulent bright green, but it really does work. It's like magic - water that doesn't make steel go rusty! The benefit is not just to the tool you are grinding, but to anything nearby on the bench that might get splashed and to the wet grinder itself, especially when sharpening wide blades as the water can sometimes splash onto the shaft and bearing.
I have my Tiger 2000 standing in a cheap plastic tray with a lip which both helps to minimise mess and also stops small items like my marker pen, slipstones, etc falling on the floor.
