I'm the fellow who posted the info on the other thread. I was in the same place as you about a month ago... AR-15 vs. Mini-14. I was also hampered by a real loyalty to Ruger stuff. Look, I won't pretend to be objective: I've decided I like the Olympic as an entry-level AR. Here is Olympic's link:

There's a link on the main page to take you to the .223 plinker description. There's more in their retail catalog section:

I've seen the .223 plinker for $529 with the lifetime warranty, 60 day satisfaction guarantee, and case. Now that was at a dealer who really wanted to get established as a distributor. If you order the muzzle brake as the rifle is assembled, it adds just $25.
If I had the extra $200 to throw at the project (as quoted by the Bushy rep on the phone), I'd strongly consider get a Bushy as well (they were my first choice). They seem to be really fine rifles and Q-Man seems to have had a great experience with his. I just don't have the moolah. I'm sure you get what you pay for, too. The difference between the Oly PCR-5 and the .223 plinker is a cast reciever set. Everything else is the same.
On the issue of chrome-lined vs. chrome alloy barrel: Remember that you are comparing the AR-15 to a Mini-14, which isn't chrome-lined either and also isn't nearly as accurate as an AR. According to my sources, if you keep the weapon clean, the lack of chrome lining won't come into play. The lining is VERY important if you plan to use the thing in combat and can't do a thorough cleaning after you use it.
Here is the Maryland AR-15 shooter's site manufacturer's comparison page:

It's a pretty nifty little site as well.
Have fun shopping and let us know what happens... Ain't it nice to be able discuss calmly?

You know, I still like the looks of the Mini-14 better...
