Awesome!!!! Congrats!
I also went from a ninja 250 to a 2003 SV650S--->N
Here is mine, I got it with 10k miles (it has 12,500 now and needed nothing as of yet, not even a chain adjustment), lowered, Yoshi slip on, frame sliders and stainless brake lines and R title for $2200 so I'd say you got a great deal too.
They do sound phenomenal and have sooo much low RPM power... I've ridden gixxers, zx6, street triple 675, 650r, z750, monster 696 and the SV is the most fun out of all of them!
Enjoy!
...sorry, I still dont know how to up-right these photos...
