If the numbers they used in the article are any indication why would I pay $3,015 for a used 5D3 when I could go to B&H and get it BRAND NEW for $3,199 PLUS the following goodies:
INCLUDES FREE ▪ SanDisk 32GB Ultra UHS-I SDHC Memory Card (Class 10) ▪ Watson LP-E6 Lithium-Ion Battery Pack (7.4V, 1750mAh) ▪ Canon 200DG Deluxe Gadget Bag ▪ Oben ACM-2400 4-Section Aluminum Monopod
Total Value $153.85
Even if I don't need the goodies I could re-sell them and make back most, if not all, of the difference.
They better offer better prices than the example or anyone with a brain will avoid the deal.
Well, you really want to use a UDMA7 CF card for the 5d3 to really get the most out of it, not an SD card (which you can't run at UHS-I speeds due to hardware). The 3rd party battery is nice. The gadget back, cool, that's nice, but cheap. And do you really need the monopod? Generally a tripod is much better except it specific cases. Plus, it's going to be fairly cheap. I'd rather invest more money into a good monopod with a quality head (or one I switch off onto my tripod).
Plus, that's probably only for the newest 5d3's. If you were to buy one that's, say, a year or so into it's life at LensRentals, it's likely a lot less.
Generally, I'd potentially use this for a lens, but that's me personally.
