I use one, Got it 2 weeks ago actually
I've got my Windows 7 installed on it and along with a few important programs /games I use quite often or that require lots of memory, The price has definitely gotten much better now, I'd say it's dropped about 30% from what it used to cost a few years ago. I can have my PC up and running in 6 seconds, I hardly ever see loading screens in any games and stuff just runs much faster and you won't find yourself daydreaming whilst waiting for something to launch up. I'd say get one
I also forgot to mention that I'd recommend buying 2 drives, One SSD for your main programs and operating system then one regular SATA drive where you can store all of your other files which you don't use as much.
