February's frenzy for reality TV has turned into March madness for inexpensive unscripted series:

• Married by America replaces Joe Millionaire this week on Fox - with originals on Monday (9 p.m., Channels 19, 45) and repeats on Thursday (8 p.m.).

• Monty Hall's old Let's Make A Deal returns on NBC Tuesday (8 p.m., Channels 5, 22), replacing Just Shoot Me and In-Laws this month.

• All-American Girl, a beauty pageant created by American Idol producers, fills the 10 p.m. Wednesday void from the cancellation of ABC's failed MDs drama starting March 12 (Channels 9, 2).

• A search for The Most Talented Kid in America (age 3-15), NBC's answer to American Idol and CBS' Star Search, begins March 21 (8 p.m., Channels 5, 22), replacing Mister Sterling, which had replaced the low-rated Providence.

• The Bachelor returns on ABC with "an heir to a well-known, dynasty-like family" looking for a wife in The Bachelorette slot on March 26 (9 p.m., Channels 9, 2).

• Extreme Makeover, a six-week series based on last December's special, takes over after Are You Hot? on April 3 (9 p.m., Channels 9, 2).

• After Married by America comes Fox's Mr. Personality (April), in which "young, beautiful and single women" will select a mate strictly on a man's personality, because his face "will be disguised throughout the dating process," Fox says.
