Going the Tex Gaggia path is a good idea.
My only quibble with the suggestions to do so is the concept of the Gaggia being "entry level".
I suppose it is because it is relatively inexpensive, accessible, and easily maintained and modified.
But it's not a machine which you will have to replace when your skills or your tastes improve. And if you buy the one from Tex, all the mods have already been done...cool.
As long as you pair it with a good grinder and take care of it ("keep it clean and keep it working" as Tex says), it could well be your first AND your last espresso machine.
It wasn't my first (I worked my way up through a lot of second hand Gaggias that I modded to make them more like the Classic), but when I finally felt like I knew how it all worked I got myself the real deal, added a PID and a Sylvia steam wand, and....I'm set.
