I'd at least give a big of dogfighting in the Eagle a go first to see if you like it. I have far more fun making money from getting the bounties from wanted ships at nav points (found near stars) and unknown signal sources than I did from trading. It's slower, but I'm playing the game for fun not to play space trucker. If you don't like it then sure, sell it, you can always just buy another.
Also to add here, extraction points can be loads of fun. Just watch out for those darn space cops.
