The Analog Devices DDS range are really nice chips and some have 
internal PLLs to get the high output frequencies with a (relatively) 
low frequency master clock.  Cheap, easy to work with, and if you 
don't expect them to give decent sines beyond a fifth to a quarter of 
the MCLK, well worth using.
