It was a bit of overkill... maybe this will be closer to what you want.
CREATE FUNCTION dbo.SingleSpace(@str varchar(8000))
RETURNS varchar(8000)
AS
--Usage
--SELECT dbo.SingleSpace('Function replaces any and all spaces up
to 16 in a row with a single space ')
BEGIN
DECLARE @s varchar(8000)
SELECT @s = REPLACE(REPLACE(REPLACE(RTRIM(LTRIM(@str)), SPACE(4), ' '),
SPACE(2), ' '), SPACE(2), ' ')
RETURN @s
END
