Is it a lot cheaper to build one from ground up.
NO. If you use quality components, you will spend just as much if not more than you would buying a gun off the rack. The advantages to building are:
1) you can do it over time; spending $1000 over several months is easier than dropping it all in one shot (pun intended)
2) you can build exactly the configuration you want, using the components you want - no money wasted on parts you're just going to change
3) you are personally able to ensure quality control... bad news is if there's a problem, you have nobody to blame but yourself, and no warranty.
