best bang for buck

I'm sure many of you have already priced many lift parts. I've been keeping an eye out for some used 4.5" coil springs but looks like I'll go ahead and buy new. Is Rusty's the best deal or have you found better? For what it's worth, I'm currently running his 3" coil springs have been happy with them even though they sagged to about 2.5".

Am I opening a can of worms? I hope not?

thanks for the input.
