  Unless tube space or balance are limiting factors, I recommend both.  The 
Telrad is always good for knowing roughly where the telescope is pointing, but 
not very good in sparse fields or under light polluted skies.  A finder is 
better for showing faint stars, but it's sometimes confusing to be sure the 
telescope is pointing where you think it is.  Together I think they make a 
great combination.
