I learned to tattoo from Jeremy Garrett a.k.a. NYARTMAN and he's one of the best tattoo artist in New York City. He pretty much uses only Micky Sharpz irons. These machines are highly sought out by professional tattoo artists all over the world. Check out his work at http:/www.nyartman.com. He's also has a great outliner made by Coney Island Freddie. It's ugly as hell and he had to do a lot of work on it to get it tuned properly but after that it's a beast. Another place to get very good machines are www.supplytattoo.com.Their machines are basically American knock offs of Micky Sharpz's machines and are just as solid. Another solid machine is the Time Machine Fusion.
National machines aren't bad but in my opinion they are quite in the same category as the other ones I mentioned above. They use to be great but compared to so many new designers who are producing excellent machines like Aaron Cain, they just don't compete anymore. Stay away form any of that crap from China being sold on ebay. Some of them look great. I bought one because I figured the Chinese have been tattooing longer that U.S. has been a country so how bad can they be? Very bad and totally useless, the coils over heated to the point that it melted the shrink wrap cover on the first day of use. Also Huck Spaulding machines and kits aren't worth your time, don't waste your money.
Many factors might affect a person's decision for a tattoo machine. For example, the cost, the quality, the brand, and the shape should be taken into consideration. There are many kinds of tattoo machines such as the liner machine, the shader machine and so on.

Premium Irons cut back, never had any better then that liner in more then 12 years tattooing
if your looking for a good machine i only use machines from borg tattoo and infinite irons dave ritchie at tat matic makes some killer machines as well ive never had any probs with any of mine
A tattoo machine's speed is so very widely variable that an estimate would do no good. You could use a weak coil machine with a lot of spring tension on a low power source and it will go really slow. But say you use a double contact liner at high power and it goes fast. Even a single machine can be a slow shader or a fast liner. You'll never find a straight up answer, sorry.
never
with a tattoo machine. this question is entirely too vague. go get an apprenticeship and ask your teacher.
With a tattoo machine.
Outlines.
This is unique to every machine, artists technique, design, and client. Do an apprenticeship
chances are your outline is done by a 5 or 7 liner (5 or 7 needles grouped tightly together) and your shading/color fill is done with a 7 mag or 14 mag depending on size of tattoo
Without knowing the specs of your power supply, I can't rightly say, but the tried and true tension test should give you an idea.
