Lumix GH3 Economic Lens?!

Sean, I really appreciate your informative advice. I have to say I've been there. I should have explained in my question above. I bought the GH2 and returned it after about 10 days. I could not accommodate its shutter noise and my still images could not be up to the quality I want. I know people do great photos with it but I just wanted the option of silent shutter and, more importantly, my hands grip on the camera was not comfortable or practical. I had other reasons. Long story short: I returned it with the 14-140 lens it came with and got the GH3 body for same price. I am a film student and aspire to collect my lenses in fairly short time over the next 1-2 year. So money might be an issue but not permanently. I'll start with the cheaper one but then I will know what I exactly want from among the more professional ones. Does that make some sense? I thought I better keep a body I can be happy with over the coming years than one I already didn't like in 10 days. Thanks for the advice about the gear too. I will have to do that also gradually over coming months through eBay and deals I see locally.
