It depends what kind of budget you're looking at as well. Wacom is one of the most known graphic tablet brands so usually a lot of people get them, however they can become pricey. I started off with just a simple Bamboo Tablet (PEN AND TOUCH VERSION) from Wacom (was around the $140 mark, but I live in Aus, it could be cheaper where you are) and that's been with me since 2010. It's a really good beginners tablet because you can get pretty comfortable with it quite quickly. The hotkey buttons on the side are quite useful as well, and of course you are able to customise it! When using photoshop, or any other design program, it registers sensitivity quite well, so you are able to see the strokes differ depending on the pressure you put while using the tablet pen. They do come in different sizes I believe! I got the smallest one to fit my budget since I was younger and just started off with a job, but it gets the job done. There are also brands such as Adesso http://adesso.com/products/product-list-20.html, and Genius Easypen http://www.geniusnet.com/wSite/ct?xItem=46752&ctNode=174. I can't personally tell you how good these because I've never had them but I'm sure they're probably cheaper than Wacom ones. If you feel like spending a bit more though, the Intuos Wacom tablets come in a larger range, and more functionality. It also takes in a lot more pressure when you're drawing so it gives you a larger variation of linear strokes.
