It's up to you if you have the money to spend. But the advice not to buy anything that cant help you at lvl50 is good advice. Being a big trekkie, I've put in a bit of real money for zen. Mostly for account unlocks as well, but I have also purchased 2 ships so far. I've been happy with my purchases. Personaly, I'm not sure I could spend money on anything like uniforms, though I would really like to get TNG uniforms. But I wont spend anything on that. It's really up to you and what your willing to spend and put into the game. Buying the NX-01 to cruise around in would be fun but remember, whatever the cost of that ship, youre only going to get a very limited time of play to use it before its just not usable. I kind of look at it like a rollercoaster or some type of ride. Your paying to use it and its fun but it will be over soon and you dont get anything else back for what you put into it. Just make sure you think it over before making any decisions.
