I had super-auto Gaggia Synchrony Digital for over 8 years and have pulled over 18,000 shots with it so you could say I know little something about super-autos
They may pull good shot once in a while. If you have fresh coffee and moon is just right they may pull a good shot. But on my machine lately I noticed that our lattes are not that good and I tried drinking espresso without any additives. Belch, I wanted to puke. Honestly, it was that bad. Horrendous. That's how I ended up buying Quickmill Alexia and it was great choice. I drink now espresso straight and taste is addictive. I grew up drinking espresso and Turkish coffee so I was really missing this...
Anyway, if you are pressed for time I can highly recommend Aeropress. It is great little device that will make very good tasting coffee super easy. Preparation is minimal, clean-up is minimal, taste is very good and process if forgiving. Aeropress is cheap and you can buy a good grinder if you want with it and use it later when you have money saved for espresso machine.
I am saying this fully aware that I made over 18,000 shots on my Gaggia, but I wish I bought good semi-auto machine and grinder right away. Back then, I had similar concerns that you do now... But even at $1 per shot, I saved over $17,000 vs drinking at Starbucks. So even if you spend $2000 on machine and grinder over couple of years you will be far ahead on savings. Heck, $10,000 spent on machine would still put me ahead over 8 years... Plus you will be drinking better coffee...
