The Klark Teknik DN360 (and earlier DN30/30) are active filter 
circuits, and sound and behave decidely different than the DN27A which 
is inductor-based.  I personally like the inductor type EQ's for 
certain things, and own Altec and White passive EQ's.  You can't call 
them graphic since they use rotary controls, but they (like graphic 
EQ's) are fixed frequency and fixed bandwidth.  For parametrics I like 
SPL, TC, and Midas EQ's, but that is a whole different world than a 
graphic.  And for the money the older Furman parametrics are 
surprisingly musical sounding.

The White's are particularly inexpensive on eBay and elsewhere as used 
items, and are quite clean.  There are other bargains to be had out 
there.  A quick search found this:

I would stay away from all of the music-store type products as they 
tend to be pretty poor performing devices.  Other than brands I 
mentioned the Rane, BSS, Audient, XTA, ARX, Ashly, some dbx, Symetrix, 
Urei, Orban, Altec, Oxmoor, IRP (very cool transversal equalizers), 
Meyer, Apogee Sound, Crown, and a few others are good. I'm not even 
mentioning the REALLY good stuff like Manley, Massengberg, etc. as that 
is a whole other thing.  In my personal (and experienced) opinion, if 
the company made guitar effect boxes, don't buy a pro sound equalizer 
from them.  Not flame-baiting here... your mileage may vary.
