Good work son!!
I like that 3100DVD alot, I tossed the 4100DVD idea but don't like the moving screend. Also the 3100DVD looks cleaner IMO so its in my future.
To install a lowering kit should run about $300.
Yea I looked at the 4100DVD too, but it is not worrth $100-150 more IMO. Both screens have the same resolution too even tho the 3100 is 1.2 inches smaller
