Porter Cable makes 2 very similar buffers, the only difference is the counter weight inside and it wouldn't really make any difference in how it works, the 7336 and 7224. The G100 from Meguiars is a 7224. If for some reason the psycological effects of not having the exact same counter weight bothers you, you can get replacement counter weights for a few dollars. The advantage of the G100 if you can get it at a good price is that Megiars warranties it for life, comes with a proper backing plate and 1 pad.
