Hi Nurjrk,
Can't really compair prices as I am up north in Canada, but I find that if you chat with guys that are local or if there is a club in your area you can get amazinig deals with used stuff.
I ran into a great guy over here and he was cleaning up and gave me a 50 gallon for nothing.
Now I was REALLY lucky with that but lots of people are upgrading, downgrading moving or just getting out.
So figure out what you want, and pick up the parts as you go. Save lots that way.
