Myself, I went with the Painless setup because I liked the idea of having the firewall plug, like original, to connect the front harness to the inside main harness. Alot of the competition are hard wired together (no front or rear, all in one harness) and you have to fish the wires through the firewall and I did not like that. I think that is one reason for some of the other harness' being under $250.
I looked at the Ron Francis setup (online) as well but liked the Painless setup better, not because it was less.
Just my opinion.
BTW, I paid $379.99 for my harness, with the A/C harness kit from JEGS (free 2 day shipping).
