I bought the Pioneer ex online from Dick's Sporting Goods as I received alot of gift cards for Christmas. It arrived in about a week and a half and came with a carrying case and snooper.
It works really great. I have only had the chance to use it a few times due to the crappy winter in KY this year. I have found several interesting old coins and brass fence decorations so far.
In summary, the Pioneer ex is a good first timer and a headphone jack is elementary to put in. You probably have the parts to do it yourself in an old radio or something.
