Glenn, don't over look the two Fuji SC lenses either. I bought the X-M1 & SC16-50 second hand for $350 Ivia the FB group Fuji X Photography, "unwanted present") as a try out for the format/system to see if I liked it. Arthritis is getting me and I cannot carry the heavy stuff any longer. The 16-50 is an excellent lens and I have bought the 50-230 also.
That said, I have invested in an 18-55 from ebay, waiting for delivery as we speak. It's a lens very highly spoken of on the FB group (had lots of great images) and forum. And last week I scored an X-T1 with 4 batteries, MHG-XT Large grip and travel/car charger as well as the standard one, all for $957.00. So I recommend buying used, more bang for your buck, even if you have to lie in wait at strange hours for auctions - definitely worth it. Loving the X-T1 now I am getting used to the quirks - I had a lot of trouble finding how to set it to Manual and working out how to get into RAW format.
And yesterday I bought a second hand handbag from an op shop and it ALL fits in, with a long strap to sling across the body. Doesn't even look like a camera and I could carry it forever.
Very, very happy with the Fuji X system. But eagerly awaiting the promised 100-400 in 2016. And there is a good fuji users forum, very helpful lot and active forum.
