I should have mentioned I generally double the wattage when I replace resistors. 1W for 1/2W, 2W for 1W etc.
I use the PR01. PR02 and PR03 series from Vishay. They are a reddish brown rather than bright blue and the color bands are bright and clear. The 2W are similar is size to the old 1/2 watters.
Also very reasonably priced. Often as little as $0.02 each on sale. Available at Allied Electronics, Mouser and Digi-Key, Newark etc.
