I ordered mine and should be getting it next week. I don't know how much I would use it... but it's basically just a backup body in case anything happens to my 5D3. I also just got the 40mm pancake and was thinking with the small size, I could always leave the SL1 with the 40mm in my car so I will always have a camera at all times no matter where I go.
I generally never take my full bag of gear out unless I have a shoot scheduled. With this small setup I can always have an SLR ready.
I posted this on the previous thread and the deal still seems to be available:
Read on Slickdeals and saw Adorama is also offering the same price PLUS 2 additional accessories: a 16GB Lexar SD card and Lowepro Toploader Zoom 50 AW.
Direct link: http://www.adorama.com/ICASL1.html
Note: It does show as $449 on the product page, but when you add to cart and then check out, it'll show the $369 price.
They offer free shipping and depending on where you're shipping to, no tax. I'm in California where Amazon now charges taxes but Adorama doesn't.
