I've never had problems with condenser mics. Granted, I've been doing voice acting and music recording for many years, so I understand the potential drawbacks. Still, I would rather have more editing to do in post and have great audio than use a dynamic mic and have (very slightly) diminished quality.
Qualifications for part D include having Part A, Part B and/or Part C. If I am eligible when does it become effective? Medicare becomes effective when you turn 65, the first day of that month. For example, if you turn 65 on October 20th, 2009 your Medicare coverage would have become effective October 1st, 2009. There are also general enrollment periods from January 1 to March 31 of each year. If you choose to enroll this way, coverage becomes effective on the first of July of the same year.
Most Americans become eligible for Medicare at age 65, and sign up for Medicare during their Initial Enrollment Period. If you enroll during your Initial Enrollment Period, you should receive your first Medicare card in the mail within about 30 days. Even if you are not new to Medicare, there may be times you need to apply for a new Medicare card.
