The stamped steel wheel guards are not as sturdy or easy to remove as the cast iron guards on other manufactures more expensive models. The DW758's guards have screws on the top and bottom, instead of on the side, which can be difficult to remove when the grinder is mounted to a bench. A small right-angle "Yankee" ratcheting screwdriver makes bottom screw removal much easier and more practical than unbolting the grinder from the bench to change wheels. This probably won't even be an issue for most users, given the relative longevity and infrequent changing of grinding wheels with normal use.
The DW758's shaft bearings are sealed and require disassembly for lubrication. DeWalt recommends having the bearings serviced by one of their Authorized Service Centers every six weeks to six months, depending on the severity of use. This could add up to quite a substantial cost over the life of the tool, given the minimum "bench fee" most Service Centers have, as well as through lost productivity to businesses from having a tool or piece of equipment out of service. For a shop tool with a recommended maintenance schedule this frequent, it would probably be better if the unit had capped grease fittings and plugs to allow relubrication as required in the shop, without having to remove it and take it to a service center.
The grinders tools rests work well, are sturdy, and can be tilted with the use of the supplied allen wrench to change the grinding angle, which is a very useful feature. The unit comes supplied with 60 course-grit and 36 medium-grit wheels installed and can accept other 8" wheels with a face width of up to 1" and wire wheels with a face width of up to 1-1/4" as well as cotton buffing wheels.
I have no problem at all recommending the DW758. The unit seems very well made, especially considering the modest price tag, and will no doubt last through many years of hard use.

A superbly built grinder (Rating: 5.00)
Review : ...this is a beautiful piece of work. It is well built and remarkably well balanced such that I really don't need to bolt it down. Its bearings are perfect as it seems it takes forever to stop once the power is turned off. The wheels are well matched for general use and fairly easy to change once the small screws holding the wheel covers are removed. The tool rests are sturdy and steady and easy to adjust and they stay put. I use it all the time with great results in my home shop. My only suggestion is that a work light should be included and it would be handy if there were a 2nd speed. Overall a real bargain for this 8" grinder.
