I suggest looking for an 8" regular grinder, one with a fairly beefy motor,
that'd be likely more evident on the 6" ones, where the motors can be undersized looking,
but probably the case with the 8" versions too.
If you can one used, with good amount of the wheels for cheap, then that's what I'd be looking for.
I made a Wolverine style tool rest for mine, it makes it very nice to use for chisels or plane irons.
You'll might use a grinder a whole lot if you get one, what's not like the slow speed Tormek types,
which need to be set up, for the likes of awls punches, drill bits, garden tools, etc.
some rough kinda stuff wot might gunk up or unevenly wear a real expensive whetstone wheel.
Another thing what's worth consideration is the positioning of the tool,
lesser height, equals lesser amount grit shed, and worth noting the white or pink regular bench grinder wheels, tend to be for fancy tools only, and are worse for that compared to the bog standard.
I have a bench about knee height which the plywood plate gets clamped to, I'd choose something like laminate again, as it is a bit of a pain to sweep out grit.
Wherever you choose, best to have safe provisions for a water bucket very near the tool.
I use half an old 2 liter bleach container with a stone, on the floor,
If you're thinking of turning, then that's where one might want to research.
Good luck
Tom
