If you really want a new ship at 50, you can always check out the exchange. There are mirror ships that aren't so bad for relatively cheap. I think the mirror science recon was going for about 70k ec. Very affordable. It's not a great ship, but it's not terrible either. That should tide you over for some time until you figure out if you wanna spend a little money and get either some fleet mods for a fleet ship or just get a ship from the C store.
Yeah, I would say check the exchange for the mirror ships. They seem to be better then the generic t5 ships and there are like 4 of them choose from. Each seem to go for under 100K ec so its really cheap to try them out.
Find one you like, have that hold you over until you grind some Zen and pick up a ship off the Cstore that grabs your eye.
