The reason I did that first was because I wanted the system to be as capable as possible of handling the next mods I did. Also I got a good deal on a "used" but never used pump and I/H from a forum member.

If you have the paitence and are limited on funds, look around in the parts for sale area and you can find some good deals. Of course new is fastest and the vendors love it so I can't knock that route either.

Good luck
