Which nikon camera should I purchase?

I currently have this camera:
http://www.amazon.com/...004H8FNNA/

And I'm debating saving up for a dslr, but i'm also a beginner at photography so I was considering this one:
http://www.amazon.com/...00427ZLRO/

And if I did get a dslr, I'm not sure what one to start with, but I was thinking the d3100? Also I'm awful at saving money and I have enough for this one. And if I wanted a dslr I'd have to wait another year or so. Do you think this one is worth purchasing and would help me grow as a photographer? Or should I just wait a year for the dslr?

Nikon D3100 is a good and affordable entry level DSLR to start with, with tons of features, and a great value for money.

Nokin Coolpix P7000 has professional looks and features, but it doesn't have a CMOS sensor. You may consider Coolpix P500 instead.

The Nikon P7000 is a great camera, but if you want one at the Amazon $229 price, you should buy it now rather than later. When they are gone, they are gone.

The P7000 is on close out due to it's replacement by the P7100. The P7100 is almost identical to the P7000, and really should have been called the P7000 v2.It uses the same sized sensor, and has most of the same feature set. The minor differences in my view is not worth the $270 extra the P7100 would cost.

I own the P7000; it is one of 6 cameras I own, along with 2 Nikon DSLRs. I use the P7000 as a backup to my DSLRs when I can't use them for whatever reason. Often when I'm on vacation, it is just too hard to take a DSLR everywhere, and when I can't, I use the P7000.

While the P7000 is not a DSLR by any means, it does have many advanced features that DSLR owners appreciate. And at the very least, you could learn a lot about photography by using the P7000, and then until and if you eventually do go to a DSLR, you will know how to use one without having to learn everything.

The P7000, while it's sensor is smaller than a DSLR, the P7000's sensor is 1/1.7" which is some 40% larger than the most compact cameras.

If you do decide to go with the P7000, know that one of the reasons that it is so inexpensive is that over it's short life (it was announced in Aug of 2010), it has not sold that well because the first few cameras that came off the assembly line had some issues. Nikon released a firmware update 1.1 in Dec 2010 that fixed most of the problems, and a second firmware update, 1.2 in Dec 2011 that corrected the remaining problems.

So if you buy a P7000, be sure to update it's firmware to v1.2 before you use it.
