Okay, here's a list of mics that you should consider.
Rode VideoMic
Rode VideoMic Pro
Rode NTG-2
Audio Technica AT897
I recommend these for their audio and build quality, and because they will be compatible with future purchases. They all have a battery powered phantom power scheme. The NTG-2 and AT897 will need an XLR to mini pin (3.5mm) convertor/adaptor.
Although it sounds decent for the price, the ATR6550 should be considered a "disposable" as it cannot be repaired once it breaks.
Solid production sound is much, much more than the mic, it's aiming the mic correctly. Proper aiming is from above the actor and pointed at the notch at the base of the throat. You should read "The Location Sound Bible" by Ric Viers; a solid introduction to production sound.
Oh, your English language lesson for the day....
Don't know if you just tapped the "T" twice, but it should be later.
Mics are put into a shock mount.
