That's a great price on a beautiful AR. And it looks good next to your CZ!
I myself was trained on the M-14 therefore I naturally prefer the open bolt design which comes from the M-1, which is available on the Mini-14's -- simply because it is then easier to clear a jam.
It's amusing how attitudes change. As more and more shooters arrive who are completely unexposed to the M-1 and M-14 original designs, the closed bolt of the AR-15 designs cause less concern for them.
Still, if you love your AR and get really good with it, that's what matters most.
