Need a bench grinder for sharpening mower blades

The last time I had my mower blades sharpened, it was $8 each. That's about half the cost of a new blade, and up considerably from $3 a decade ago. So it's time for me to get a bench grinder so I can sharpen my own blades. These are the blades on my mid mount mower, not the big MX6 rotary cutter.

I got a flyer from Northern Tool with some discount coupons it in. They have a 6" grinder on sale and you can also apply the coupons. Now I don't want the one they show because I'd like one with a light on it.

Now keep in mind this is for weekend warrior use. I don't even have a welder (there was one for sale in the catalog, but I'm not going there....). I've got a 4.5" hand held grinder, but it sure seems like using that on mower blades that are off the mower is going to cause more trouble than it solves (although they are tempting to use to touch up the MX6 blades). So what should I get?

Size of the grinding disk?
Work light?
Stand or Table top mount?
HP of motor if it matters?
RPM?
And all the other stuff I just don't know enough to ask?

TIA and when the mowin' is over I can't wait to get to the seasonal grind :laugh:.

A number of years ago I ordered a Delta 8" bench grinder with stand, and ended up with a Delta 10" grinder with stand. I agree with Kenny about not wasting your time with a 6" grinder, and the stamped sheet metal tool rests. I'm really glad I ended up with the 10" grinder by mistake.

I looked at a Jet 10" bench grinder a few years back and liked it better than my Delta.

If you use a stand, bolt it to the floor as these things are like drill presses...top heavy.
