Acoustic: I recommend a Yamaha solid top acoustic guitar. This guitar plays just as good as some that are many hundreds of dollars more expensive. It can be difficult to manufacture quality acoustics at low prices due to the importance of a solid top finish. When I was in college I scratched together the cash to buy a handmade acoustic guitar that was over $1,000 (I won’t mention the brand) but that guitar was nowhere near as good as this Yamaha.
Learn how to transition to different chords. One way to become proficient quickly is to learn how to transition between the various chords quickly. These transition periods are often the hardest for beginners to play when they are starting off. The more you practice between switching to different chords, however, the better you'll get at doing it in songs. Practice switching between open chords like G, A, E, and C. 
Electric guitar: Well the world of electric guitars is in some ways more complex, as there are all kinds of different looks and technologies. And it’s not good enough to just have a guitar, you need to buy an amplifier as well. I will just recommend mid-level stuff that’s worked for me based on my preferences, but if you like “stuff” and collecting gear, you’ll find playing the guitar to be a deeply satisfying hobby :)
Manage the finger pain. There'll be a point at which things will seem bleak: you can't quite get to each chord as fast as you want, your fingers are killing you, and it seems easier to put the thing back in its case. The reason most guitar players stop playing a few weeks in is that it hurts. After a couple of months and years of playing, callouses will build up on the fingers of your fretting hand that will greatly reduce the pain of pushing down the strings for long periods of time. Everyone who learns to play the guitar has to deal with sore fingers at the beginning. Learn to love the pain and associate it with everything that you love about music and the guitar.
Now many people are going to ask about other brands, like why don’t I suggest Gibson guitars? It really is a personal taste thing, and it’ll ultimately depend on yours. Perhaps by the style of music you play or the artists you admire. For me, Fender guitars represent the best in quality and feel. Many Gibson style guitars have fatter necks, bigger frets, are heavy, and feel and sound “muddy” to me, whereas the feel of a Stratocaster– light, slender, classic– feels, plays, and looks fast. :)
