It's actually $190 to get everything right now if you do the entire buy two core sets type thing. What I did was buy one of everything to get my collection up and it's been going against two of everything so far, which has been close. Deck building skills are heavy in this game to know what you want, but when Balance of the Force (only need one) comes out, it jumps up to $220. That's the competitive way.
If your going casual right now and want everything, then that would be one core set and one of everything else which comes to $140, or $170 when Balance of the Force comes out. That's the casual way. That's what I've been doing since July and it's been fun. Now I'm ready for competitive play but my play group isn't big enough for it sadly, which, is why I'm just going to get another core set this month with the new expansion pack.
That's two ways you can go, and as long as your playing for fun, both ways are awesome. Give the game a try and if you get into it, then choose which way you would like to go. For me, casual was fun because I play Magic: The Gathering and Weiss Schwarz tournaments ,so I wanted to do some casual stuff for a few months. I know my entire playgroup went competitive right away and I'm the only casual guy there as of right now. Lol. Hope this helps. =)
Edited: I play a game call Weiss Schwarz and for one deck, just one deck, I dropped $300-400 on booster boxes and working on a second deck from Madoka Magica. Truly less expensive here than Weiss Schwarz; just you are picking a good LCG to begin with. It also helps if your a Star Wars fan and know the lore as well. =)
