Coffee!! Now you're talkin'!
I don't have a machine, can't recommend one in particular, but suggest checking the reviews, consumer reports, etc. It's just a matter of shooting steam through a charge of grounds, or through a side pipe for foaming. It is with disdain that I look upon those machines that work with those creamer-sized pods!
Concerning the brands you've already tried, I'm not seeing much outside the traditional brands, and you didn't mention whether you've tried different brewing methods. Moreover, I'm speechless about your affinity for gas station and machine brews. In college, there was a thing we called the "hot sludge machine", which also dispensed chicken soup and tea, your choice, but seemingly all from the same nozzle into the cup.
First, get yourself a plunge pot. Don't worry they're generally inexpensive! Grounds steep in the full charge of water for three minutes, then the plunger/screen is pushed s-l-o-w-l-y down, taking all the grounds to the bottom. This method yields more of the aromatic oils than coffee run through a filter.
Next, explore the world of different roasts. I recommend whole bean, grind as you go. Try the darker, espresso and Italian roasts. If they're too demanding, throw in some 8 O'clock beans to mellow it. Hot water can turn down the strength if you've gone too far
Different lighteners have different flavors. Heavy and light cream, half and half, whole milk, simmered whole milk will all influence coffee to taste differently.
You now are presented with a plethora of combinations and options! Rich, you gotta check this out!
