Using OUTPUT to set up foreign keys' data

So, I was looking at a process that inserts records into table A (one at a time), then uses SCOPE_IDENTITY() from each insert to get the ID and uses that for the insert into table B, in order to provide a cross-reference tabled (foreign key).  

Obviously, there's a better way - OUTPUT, usable since SQL Server 2005.

An example.  We populate “blah”, then use the values from that to insert into “blah2”, with a foreign key ID of the first table.  

CREATE TABLE blah (id INT IDENTITY, logon_name VARCHAR(50))

CREATE TABLE blah2 (id INT IDENTITY, blahID int, dn VARCHAR(200))

INSERT INTO blah

      SELECT TOP 10 name FROM sysusers

INSERT INTO blah

      SELECT TOP 10 name FROM sysusers

DELETE FROM blah

--incrementing to show different ID values.

DECLARE @insertedlist TABLE (id int, the_logonname VARCHAR(50))

INSERT INTO blah

output inserted.id, inserted.logon_name INTO @insertedlist

SELECT TOP 10 name

FROM sysusers ORDER BY createdate

INSERT INTO blah2 (blahid, dn)

SELECT insertedlist.id, sysusers.uid

FROM @insertedlist insertedlist INNER JOIN sysusers

ON insertedlist.the_logonname = sysusers.name

SELECT * FROM blah

SELECT * FROM blah2
