How To Email Completion Messages From RESTORE Commands?

I need to build an automated email that gives the completion messages
when a database is restored (i.e. "Executed as user: sa. Executing
RESTORE DATABASE DB1 FROM
DISK='h:ackupsDB1DB1_db_200411082056.BAK', RECOVERY [SQLSTATE
01000] (Message 0) Processed 3816 pages for database 'DB1', file
'DB1_Data' on file 1. [SQLSTATE 01000] (Message 4035) Processed 1
pages for database 'DB1', file 'DB1_Log' on file 1. [SQLSTATE 01000]
(Message 4035)")

Currently, the Job History box contains it, but I'd rather get it via
email. The base restore statement works, but it gives me a "Cannot
perform a backup or restore operation within a transaction." when I
try to run it as below.

works:
[build @RestoreCmd]
exec (@RestoreCmd)

doesn't:
[build @RestoreCmd]
create table #Error_Finder (listing nvarchar (4000))
declare @Errors smallint
insert #Error_Finder exec (@RestoreCmd)
EXEC xp_sendmail @recipients = 'dba',
@query = 'SELECT * from #Error_Finder',
@subject = 'SQL Server Restores'
drop table #Error_Finder


Any suggestions? My next thought is to start selecting against system
tables in msdb. It looks because the Insert can fail, it's a
transaction.
