The only way that I'd touch J&K is with a ten foot pole...
that's got a LIVE hand grenade attached.
In looking at this eBay auction, they bundled that camera with a lot of real
trash items that you don't need or want. As such, while that $880 price sounds like a great a value with all the extras, let's take a look at them:
Two UV filters - - for no-names and in these sizes, these are worth $5 each.
Two folding lens hoods - - I made the mistake of buying one of these awhile ago and found that they are utter garbage. Real world worth is zero.
2GB CF Memory - - its standard speed! That is such "old tech" that they're starting to get hard to find. Note that the colors suggest SanDisk brand, but the image has no name on it. To say that this card is worth all of $15 is generous.
USB Memory Card Reader - - call it $8
'Carry Case' - - on the streets of Brooklyn
this bag is $5.
Tripod & Mini tripod - - again really cheap stuff. $10 each (and do you really need both?)
Lens cleaning kit - - $2, tops.
(Subtotal: $60)
I'm going to ignore the 'free battery grip' as a feature, as I'm going to assume that any order from J&K contains something that isn't going to work, be the wrong product, etc. Their reputation simply is too utterly bad.
So in getting rid of this whole pile of abysmal quality & BS Accessories and using B&H as a reputable dealer:
$659.95 - price for XTi body
$129.00 - Sigma 28-70 (cheapest lens that Sigma sells)
$139.00 - Sigma 70-300 (second cheapest lens that Sigma sells)
This all sums to $928. As such, this means that all of the risk that you're taking through eBay with dealing with a known-questionable dealer versus a known-good one is going to save you only $50...although I'd probably be more inclined to get the body with the 18-55 kit lens for $717, and the Canon EF 75-300 ($150) is probably the equal to the Sigma. This combination would add up to $867...
