Re: Is a CETME worth an AR15?
As has already been said...if it has Century Arms or CAI anywhere near it...RUN AWAY. They are generally garbage and not fit for tomato-stake duty, but less as a firearm. If you want a quality, HK91 reproduction, then the PTR-91 series rifles are the way to go without having to spend HK dollars.
That said, to get any 91 clone to shoot like a quality .308 AR takes a whole lot of time, money and patience. Most people that I know would generally be better off with a large-frame AR than the clone 99% of the time.
As for your AR...in the current climate, I'd think twice before selling OR trading it. If you want something else, by all means go and get it if you have the funds, but scrapping a perfectly decent AR in working order right now isn't the best of ideas unless you want to engage in price-gouging on the unwashed masses and then put those funds into something else. Either way, I'd buy first and get your new rifle in hand before selling off your AR.
