While the naming convention maybe different, the Casio WK-7600 is essentially the same as the CTK-7200, with the main difference being the extra octave that the 76 Key configuration provides.

This is essentially a version of Casio's flagship keyboard, carrying the same incredible amount of sounds, effects and arranging but with more notes readily available to play with. The same audio recording features that let you record vocals and an instrument straight to the keyboard is available as well. More importantly, it gives you all this while keeping the unit reasonably portable and affordable.

Pros

The overall response to the WK-7600 is generally positive, with many being impressed by its massive feature set, one man band accompaniment and recording capabilities. While Casio keyboards are not necessarily popular for their sound, the WK-7600 got quite a lot of high ratings due to the quality of its sound, specifically for its customizable piano and organ tones. Even experienced musicians were floored by how good the sounds of this keyboard are, and add to that the fact that you can further sculpt the sound to your preference.

Cons

Some users commented that the manual is not as beginner friendly as it should be, thankfully, there are a number of youtube videos detailing the use of the keyboard. As expected there are those that find some of the sounds to be lacking, but they do appreciate the other sounds, specifically the Hammond organ ones. The lack of old MIDI ports also came up, since this one also utilizes USB MIDI.

Overall

If you're looking for a 76-key performance keyboard that can also double as an arranger keyboard for simpler tasks, then this is a decent option, however it's no longer on our recommended list because as of October 2017 there are now more highly rated options available which you can find in our guide to The Best Portable Keyboards - MIDI Enabled Under $500.
