Crucial factor would be size/footprint (small kitchen) and secondary it should look "nice" (not too much metal/shiny brass, and not too "plasticky". :)

That is part of the reason I went with Baratza Preciso. Of course the fact that it was a good grinder and I could get a refurb fully updated also helped. WAF is very important if you are going to use the grinder and leave it on the counter. It still needs to be a capable grinder. Good luck with that, WAF :)

Hi Phil, I have one of the Gaggia Coffee machines too. The spring and ball valve regulates pressure for this machine along with a non-adjustable over pressure valve. Since this machine does not have the three way solenoid water will stay on top of the pressurized puck and the pressure will need to bleed off more slowly. This has a benefit though - you can turn off the pump after a few seconds to create manual pre-infusion.
I am not familiar with the grinder you mention.
I chew coffee beans with my teeth while gargling with 195 F water to enjoy coffee. What is this "coffee brewing" device you speak of?

Hm, pre-infusion is a new concept for me ... That means you turn on the pressure some (2-3?) seconds then off. Then wait a bit before turning it back on for the ~25 secs?
My grinder is this: http://www.nivona.com/en_CafeGrano_120.AxCMS?ActiveID=1219 I have been able to make really good espresso from it, but the "clicks" for adjusting is not really fine tuned (as it's not an espresso grinder, but a coffee grinder). I have used it to grind lots of great coffee for french press, aeropress and pour over ... :)

Here in the USA a product called the Capresso Infinity looks pretty much the same. If you search Capresso Infinity mods you can see how to set the adjustment to grind finer, and how to make the grinder stepless - no more clicks.

Ok, so I should try pre-infusion, then ... :)
And thanks for the tip on modifying my grinder! :) This blog post looks interesting. :)
I also just ordered a replacement water tank (the original is broken), gaskets and descaler. Hopefully even better espressos more consistently will be the norm, well in time for christmas. :)
Today I had trouble getting the doubles right (the beans are a little bit old). But I switched to the single filter and used pre-infusion (3 secs on, wait 5 secs, then as close to 25 seconds as possible for 30 ml). Got 32 ml in 23 seconds, but the taste was great! (I was tamping pretty hard.)

I have basically the same machine, Espresso Model. It took me a bit to get really good shots. I have a Virtruoso grinder and I have it set at about 9.5. I use the double filter and put in about 16-17 gr of grounds. It take about 10 seconds before I get coffee and it finishes between 23-30 seconds for 2 oz. I give it a good tamp which I tried on a bathroom scale first. As far as a wet puck, once the shot is done I open the wand valve and let the pressure out, then I remove the portafilter. It does all work, getting the grind right was the hardest.
