Does anyone have suggestions?
~~~~Hello Casandra, You are getting some very good replies from these folks. What they are trying to tell you and their answers have been consistent (read between the lines= : - ) the grinder is more important than the purchase of the espresso machine. If you are on a budget, and who isn't, I'd suggest for you to purchase a used commercial grinder first. When I was looking to get into this hobby, that was my understanding (& it still is), that the grinder is far more important than the espresso machine, for if you have a good grinder and good fresh beans to grind with, on a properly tuned $300 espresso machine, you can pull shots on par with a machine costing thousands more
The grinder I bought last April was a well used Rancilio MD-50, a new set of burrs and I had $250 into it plus shipping. i would consider the grinder I have the minimum standard. There are other brands, read all you can about grinders and be on the lookout for a used machine. Ebay is a good place to look for a grinder to purchase. Use 'commercial espresso grinder' as your search criteria, or 'espresso grinder', 'espresso coffee grinder', etc.
Now for the machine, IMO, you want a heavy marine grade 58 mm chrome plated brass portafilter, single boiler will be cheaper than HX but not always yet usually. if it's a single boiler it's a vibe pump and you want (IMO) an adjustable OPV or the ability to add an adjustable OPV if the machine does not have adjustable OPV. Why?, if the over pressure valve is non adjustable and is set at 15 bars pressure, you wont be at the ideal pressure of 8.5 to 9 bars pressure. Most authorities on espresso pump pressure agree, 9 bars pressure. go to wikipedia and type in espresso and look at what comes up. Amongst all the info the pertinent details of pulling a good shot, the pump pressure is 9 bars, water temp at 200 degrees, w/the right grind, tamp beans you'll end up with a double shot 2-2.5 ounce in 25 to 30 seconds. All this was empirically arrived at when?, late 1940's?, by folks who have forgotten more about espresso than I'll ever know= : - )
If you buy a single boiler machine, PID is nice and you can find good used machines. Remember, when you have a new espresso machine and you pull the first shot with it, it's now a used machine= : - )
so that's my 2 cents, echoing a lot what others have said, buy a good used commercial grinder for the most bang for your buck/grinder allowance, and buy that piece of equipment first. The espresso machine is the least important piece of equipment in the equation but it is nice to have PID on a single boiler, adjustable OPV, 3 way valve (but 3 way valve is not necessary for a good shot)
FWIW, I did my homework when I was getting into espresso and found a PID'd single boiler machine with the aforementioned pieces already kitted. All I had to do was to use good beans and learn how to grind, dose, tamp. I can say from 9 months experience and I pull on average 6 doubles/day, fresh high quality beans is what you want to learn to grind with. You probably know this but you can't make good espresso w/pre-ground beans
Once you get your new grinder and you have an espresso machine to pull shots with, sit down with a pound of beans and your grinder and set the grinder to the finest setting and attempt to pull a shot. If you have a good grinder, no espresso will come out of your PF because the grind will be too fine. Now open the grinder little by little until you pull a double shot and end up with between 2 and 2.5 ounces of espresso (you will need a measure-graduated shot glass) in 25 to 30 seconds (approx)
Others may have better and different ideas but this was how I was taught, and those that taught them, they too followed the golden rule (espresso)
