My dad always told me that as a general rule people don't buy what they "need", they buy what they "want".The 180 is a fine saw in it's own right!! And for the money of the 200 you could get a 361, which opens up a LOT more options. Or you could get a 180 and a 290 and probably be happy the rest of you're life!!
Buy what you want/NEED, I don't care, but to compare those two saws isn't fair!!
