Hey guys so I've decided to gear away from the traditional sketch book and what to upgrade to drawing on the computer, I was wondering if anyone knew some good tablets that you could plug into your computer via USB or whatever that would allow me to draw on it and simply transfer onto my computer.

I don't know if it makes a big difference but I am using a Mac.
Thanks in advance.

PS. Price is not really an issue but I would like something that is reliable but not over expensive!

There are many options out there. In general, a lot of people recommend Wacom Bamboo tablets. They're a lower priced tablet but you don't sacrifice much of the usability and performance.
The Bamboo Create is $199 and comes with some included software. An even cheaper option is the Splash, which is $79. You can view these and their other tablets on their main website - just search for Wacom Bamboo.

I've had a Create for quite some time and have enjoyed it (the little that I've used it anyways).

Yeah actually I just ordered a Splash ! haha perfect size, portable! allows me to do my sketching and drawing, the price is a steal and also works with MAC! (finally something does >.>)
