If money is really an issue you could always look for a used one of either. I saw a used 3DS going for only ninety bucks and a used 2DS that was ten bucks less. You're taking a risk depending on the conditioning of the product and how honest the seller is, but if you really care about saving money it could be a good investment and you can always return it. I got some good deals on used games when it came to Ninja Gaiden and Eternal Darkness.

My question is is the 3D worth the extra money?
