There is nothing wrong with Mr Beer. Many brewers got their start from a Mr Beer kit. That being said it does have it's limitations as far as the volume of beer you can brew, and the complexity of the beer you can brew.
What you really need to decide is how dedicated you would be to brewing beer longer term. I see you do not list your location. I would recommend trying to locate some home brewers local to you or even attend a home brewers meeting. If you can watch the process it will help you understand if and how you wish to pursue it. Ideally I would try to find someone who is brewing with extract. That is the simpler way to make beer early in your brewing experience.
Brewing extract will eventually require some equipment and most home brew shops offer starter kits. A decent starter kit is going to run somewhere in the $100-150 dollar range depending on the type and amount of equipment. Your most important element as a starting brewer is probably the boil kettle. Buying a nice kettle with somewhere in the 8 gallon and up capacity will allow you to do full boils for 5 gallon batches, and if you choose to upgrade in the future the kettle will remain useable for all grain brewing.
Finding and hanging out with a brewer will go a long way to help you understand how you want to approach brewing and what you will need. Don't be afraid to approach a seasoned brewer and ask questions. It's harder to get us to shut up then it is to get us to start talking beer.

This is by far the best advice go the American home brewers association web site and find a local club in your area. Don't be shy and find people willing to have you over for a brew day, one who does extract and the other who does all grain. You can save some money not buying a kit a piecing your equipment together. You will get an idea of what your in for, make new friends, and learn the proper processes. I cant tell you how much more enjoyable doing this will make you entry into the hobby. It is also very easy to get overwhelmed here at HBT and get distracted from having fun! Dont get me wrong stay, ask questions, and read read read! But I came here when I started and have learned a ton from the veterans here, but I really benefitted from the guiding an simplicity of help from my local club. That help allowed me to get the most value out of coming here an reading and posting!
