I have no idea the $ ratio on it, but based on the use/enjoyment, the best $ I ever spent was on the first .223AI I had put together. I shot more, shot at longer ranges, killed lots of stuff, learned more about reloading, learned to dial for distance and use mildot's, wife shot more, introduced friends to shooting with it...

I guess I'd have to say it cost me a lot of $ as well since I've had several rebarreled in the same chambering, but it's been well worth it!
