I am completely new to arduino, getting ready to buy my first one to make a very simple project.  I've spent hours of research just trying to figure out which arduino to buy, however the sheer number of different models and clones, etc has made my head spin.

Right now I'm leaning towards the Nano 3.0, but what I have not been able to find out is are you sacrificing any sort of functionality by going that small?  Is there things that the duemilanove or uno can do that the nano cannot (besides that you can plug shields into them)?  

Then there are all these different clones too that I've heard might be either cheaper or have added functions, are there any clones I'd want to consider?

I'm most concerned about making my first into to arduino as easy as possible.

Thanks.

PS: The project I'm making is going to be a simple remote controlled servo, that I can move to 3 specific positions with the push of the respective button on the remote control.  That way I can use it to manually press the shutter button on my camera that does have remote shutter.  One button would do the half press of the shutter, the next would press it the rest of the way, and the third button would let go of the button completely.

The nano has the same functionality as the duemilanove or uno but lacks a DC power plug and it uses USB mini rather than USB B.

The boarduino is a bit cheaper but a bit larger. http://www.adafruit.com/index.php?main_page=product_info&cPath=19&products_id=91

So what is the easiest way to power the nano with a battery?  Do you simply solder the positive and negative wires of a 9v battery (or other adequate battery holder) to the correct spots on the board?

The only way to connect the battery is through the VIN and the GND. Make sure it is the VIN, that is the only pin that takes unregulated power. I would connect it via a jumper cable or a breadboard... Soldering on the board seems like asking for problems

Then get the standard $30 arduino.
