+1 for aeropress & grinder. The aeropress is cheap, portable (just took it on a camping trip!) and the cleanup is simple. I have my brewing process down to about 2 minutes (75% of that is heating the water). The obvious downside is you can only make a single serving, but if you plan ahead and heat more water then making another shot of aeropress is quick. That, or use a ton of beans to make a very concentrated aeropress and divide between multiple cups, then add the rest of your hot water. ez pz. If you need to make a bunch of coffee, a large french press or chemex/pour-over style is just as good though the cleanup is slightly messier.
I have a decent burr grinder and a $10 blade grinder. I'll admit half the time I'm super lazy and end up using the blade grinder much to coffee elitists' chagrin. If you're drinking coffee for the caffeine and don't care so much about the flavor, preground beans get the job done of course. Drip coffee makers also get the job done but in my experience they brew the coffee at too high a temperature so you end up with super bitter coffee which will only get worse if your drip maker has a warming plate. I've only ever owned under $50 drip makers - I'd bet there is a price point where they start to brew your coffee at the correct temp. I can't recommend a Keurig because KCups are as expensive as it gets plus you run in to the same bitter coffee issues if you get the cheapo models.
