I have three magnums that I use on freshwater and reef aquariums and I 
disagree with your conclusions.  The magnums are cheap and easily 
modified to be used in virtually any manner one wants.  It just takes a 
little creativity.  I have never had any problems with them in the 7+ 
years I have used them.  Periodic O ring replacement is the only thing I 
have had to do to them.
