If you plan on using alot of copper, then you could probably use the Home Depot. Remember the type M is a little softer and probably easier to hammer out. If it is ruggedness and duablility, then I would go with type L. It is harder and has a wall thickness that is just a few thousands of an inch thicker and has a little bit more alloy in it.
Type M is also much cheaper than type L. Don't even bother with type K. That is available only in plumbing supply houses and cost an arm and a leg.
Just a word of caution on the grinding wheel. The copper can load up the wheel and create the wheel to heat up. Once hot, it can explode on one of the subsequent cuts.
You can get a decent pipe cutter for almost nothing. It is much safer and wont distort your vision. (wont explode either)
