As you are beginner (and looking at products from Simple Labs) I don't think It would be a bad idea to look at the InduinoX board by Simple Labs. It is an UNO clone (and the latest one is an UNO R3 clone), and contains many features useful to a beginner, like LED's, Buttons and some sensors attached to the board. This makes it easy to learn and saves the time which you might spend fiddling with a breadboard.
There are a lot of other alternatives, like the Freeduino USB from probots.co.in
. Unlike the InduinoX it has no additional features and is a lot cheaper (available for about Rs. 650). You can find it here at : http://probots.co.in/index.php?main_page=product_info&cPath=55_56&products_id=395
And if you are not a fan of clones I would recommend using the Arduino UNO. Even if the leonardo has got more PWM outs and more analog ins I don't recommend it to a beginner because if you kill it somehow (which is likely to happen if you experiment A LOT) .. replacing the IC can be troublesome, whereas in the UNO you can easily replace your dead IC for a new one simply at home.
