DEWALT D28110 Heavy-Duty 4-1/2-Inch (115 mm) Small Angle Grinder
$111.32
It's small, light weight, compared to professional use grinders, while delivering lots of power and lots of wheels and brushes available for various uses, including heavy duty diamond wheels. I found it very easy to use and control. The average home user will not likely find this unit lacking.

The grinder is tool-less, if you use their rubber backer DeWalt DW4945 4-1/2-Inch Rubber Backing Pad with Locking Nut for fiber discs and sanding disks or if you use their grinding and cutting wheels that have an integral nut, like this oneDEWALT DW4522 High Performance 1/8-Inch Metal Cutting and Grinding Wheel that has the 5/8 - 11 arbor. In both cases, the wheels can be installed and used with hand/finger tightening.

As far as I can tell, this grinder will accept every 4 1/2 grinding accessory wheel that is available. Many (most?)of them are marked with a 7/8 arbor, which will work fine. Just make sure that you install the 7/8 arbor wheel so that it is centered on the backer, which has a little lip at the 7/8 mark. Then install the locking nut, which also has a 7/8 lip to use on their 1/4 inch thick disc.

To use a rubber backer for sanding discs, polishing wheels, fiber discs, you have to remove the backing nut. It is retained by a rubber O ring and is easy to remove. The instructions are in the manual, but are easy to miss. There are no spanner wrench holes in the locking nut of the Dewalt rubber backer. That means you have to use finger pressure to tighten/remove it. There are other rubber backers that do have spanner holes in their locking nuts, like the Bosch MG0450 4-1/2-Inch Sander Backing Pad with Lock Nut which I think are easier to use. You'd probably need another spanner wrench for the 3rd party backers. I use this one, Adjustable Pin Wrench because it's cheap but works just fine.

You can also remove the guard, if needed to get at certain jobs. If you do, just remember that the on switch is locked on, so if you drop the tool, it could be chasing you around the room.

My only complaints are minor. I wish that there were a threaded socket on top of the grinder for the handle, in addition to the 2 on the sides. The arbor lock button is in a rather awkward place for me.

This grinder seems like a great value and I'm very pleased to have one.

Krups 203-42 Fast Touch Coffee Grinder, Black
$24.00
I was given the grinder when I stated to a friend that I was looking for something to grind whole flax seeds. The product does a good job grinding the flax seeds. It is difficult to keep clean when used in this way, however, I believe because of the seeds' high oil content. A great deal of the ground flax seeds stick to the sides and have to be scraped off sometimes with a lot of pressure. The inside can become damage by doing so and the plastic top can become scratched. Given the price and performance and my desire to consume freshly ground flax seeds I have recently purchased a second one when the original one could no longer be cleaned sufficiently.

2.25" CHROMIUM CRUSHER Premium Quality Tobacco Herb Grinder (non-aluminum grinder)
$30.00
I bought this thing about a month ago and have put plenty through it. It came super sharp and has stayed that way so far. This thing does exactly what I bought it for and my buddy seems to like it better than his Sharpstone (which I personally witnessed lose three prongs in one grind). The only downside is that it does not have a very high lip to contain after grinding. I'm not sure if every ChromCrusher is exactly the same but mine could have used a little more capacity. Takes a lot of turning which can get old, but usually your about to have some fun, so you can get over that.
