Darth Revan price estimation?

I started farming OR the day they dropped. I didn't spend a dime or crystal until the packs came out the other day. I had everyone at G11. Dropped $180, got to 6 stars. Dropped another $100 and still need 20 Juhani shards. I have 3200 crystals left though and I did get a few needed pieces of gear with all that. It's a ton of money for sure and I hate to spend it like this.. but I was top 10 in arena for months with JKR. Got a lot of crystals back over that time, around $270 worth. Obviously not cash in my pocket, but eased the pain. And - Carth lead is easily one of the funnest teams to play and really hard to beat if modded right. So if you can spend it.. go for it!
