You may want to wait for more reviews regarding even PAR coverage front to back with wider tanks.  Might be an issue with a 2 foot wide tank like yours.  I guess it might also depend on your aquascape and location of corals/clams etc. 
 
Pacific Sun units are pricey.  Most have no optics and the version with optics is even more expensive.
