Adding on to this - even a cheap burr grinder with freshly roasted coffee can open up your world.
I splurged on a Bratzza Encore years ago after a Christmas bonus, and was shocked at how much of a difference it made for my cheap automatic drip maker.
Later, I upgraded to a Chemex 6 cup pour over (with a cheap, non-electric gooseneck kettle). That system got me through grad school and several years of shit IT work. All told, for just around $250 (if you look for sales) you can start really enjoying the subtle flavors of coffee.
My setup today is a bit more elaborate, but I still regularly dig out the Chemex when I want to try a new roast.
