D7000

Here we go again.
Out shooting lately with the D3100 I purchased from Adorama for around $400 refurbished.
I found the remote I had would not work with it. The manual lenses I have will not meter.
The flash cannot be used without a cord.
And then, many dust spots started showing up in the sky shots.
Frustration ensued.
Tonight, I went to B&H and ordered the Nikon D7000.
There is a newer D7100 but several hundred dollars more and
essentially the same camera.
Will I be able to keep it and pay it off on the card monthly?
That remains to be seen.
Also ordered a spare battery since the spare battery for the D3100 I ordered months ago has yet to arrive.
Just today I was out and sure enough the battery died. No spare.
Lugging dead weight.
With the D7000 I should be able to use the manual lenses without having to
guess the exposure.
I should be able to use the flash without the cord.
It has two SD Card slots. I will be able to shoot raw in one and JPeg in the other.
It will not save weight though.
Hopefully it is not a refurbished model.
We shall see.
We shall see.
I have done this several times before and sent the camera back.
