I'm glad others explained more calmly then myself. You gotta really look to see what you are paying for. It all depends on the style of play, but no matter what all EP markers (mid to high end electros) are going to shoot just about as fast, speed is NOT what your paying for.
My old Evil Pimp shoots as fast (if not faster) then my (much newer) DP threshold, but the Threshy has a lot of features that make it a bit of a nicer marker. Further its far lighter and easier to handle and maintain.
For example with the Rail you are paying for a very high quality marker, with the reflex rail your adding at least another 150 just for milling (the body style of the marker).
