I'll second the small Harbor Freight straight and angle cutoff/sander/grinders. At $10-$20 each I've yet to have one fail and they perform reasonably well. I'd rather have multiples of those set up with cutoff/sander/grinder wheels than have to change out tooling every time I need it because I spent $125 on one big brand name.
