I have been using the Jobo system for a number of years, and before that, just about every other method of developing sheet film. In my opinion, there is none better for the price. I use the CPE-2 to maintain temperature and continuous agitation (and a large savings in the quanitity of chemistry used), but even without that processor, I find the 2521 a damn fine tank. It is easy to load, easy to use, easy to maintain and easy to clean. More, it does not leak either chemistry or light. Without the processor, you have to use a larger volume of chemisty but then, you can use intermittent agitation instead of continuous.
More, since you already have it, you may as well as use it. Good luck and I hope this helps. You won't be sorry about either using the Jobo tank or getting into large format photography.
