Nintendo 3DS

Out of all of those, Pushmo is my favorite. It's challenging yet fun (not challenging to the point of throwing your 3DS into a wall due to anger). It has the capability of scanning QR codes (those black and white square scans) of other peoples puzzles.

A site with QR codes for Pushmo is:
http://www.pocketgamer.co.uk/r/3DS/Pullblox/feature.asp?c=36101

Although there are many more sites out there that have codes as well (Sidenote: Pushmo is called Pullblox in EU, so you can either search for "Pushmo QR codes" or "Pullblox QR codes" because they all work).

And not only can you scan other people's puzzles, you can create your own and post your QR codes for people (plus you can choose to lock the puzzle, which will prevent people from altering your puzzle and trying to make it their own). Also, the custom puzzles always have a solution (or solutions) because they require a person to solve the puzzle before giving the puzzle a QR codes to distribute.

Out of all of those games on your list, Pushmo has the most replayability and it also adds the option of creating your own puzzles, which is fun if you fancy yourself as the creative type.

Well, I've decided. I'm going with Dillon's Rolling Western and Pushmo. I've got enough for both and they look like they got the most replay value. Thanks again for the answers.

Excellent choice TC
