Help needed with Jobo gear please

I'd appreciate a little guidance from any members who know the Jobo systems.
I've just bought a CPE2 processor and will be collecting it in a few days. This one doesn't have the lift kit attached. It's also lacking a tank and reel/s. At present, I'm only interested in developing 35mm and 120 film. In order to get it to a usable option, I've been trying to understand the system and it seems that it's so flexible and adaptable that the options are confusing and a little overwhelming.
So, what I (think I) do understand is that there are tanks with a larger diameter that are primarily designed for sheet film - 25xx series and the smaller ones, the 15xx series which are best suited to roll film. The two different series can be used with roll film, but the reels are of different diameters and the difference in price is significant..
I have also gathered that the basic tanks are intended for manual use but you can add a different type of lid with a cogged top to allow it to be used with a rotary machine fitted with a lift device. Alternatively, if you add a magnet to the base, you can use it with a machine without the lift.

So, I need a tank with a magnet on the base and some reels to suit.

It turns out that I have a Jobo tank already!
It is a 2523 model (one of the large diameter ones). It has both a magnet at the base and a lid with a geared cog on it. I have no reels.

So, my question is this: Is it OK to use it on my machine as it is now. I would need to use the magnetic base to attach it for rotation, but would it be reasonable to assume that the lid I have will be fine as long as I don't tip the liquids out at the wrong time?
Secondly, will the reels for the smaller 15xx series tanks go onto the centre spindle or will I have to buy the bigger and more expensive type? It feels like the cost of two big reels will be pretty nearly the same as the price of a smaller 15xx series tank (which comes with a reel) and a second reel. I already have magnet which I could swap to a new tank.

Hopefully I have explained the above well enough for the folks with the answer to understand!
 
The Jobo tanks with the magnetic attachment require a lid (red plastic), as the cog lid will probably leak chemicals into the processor bath while rotating. On the CPE2/CPP2/CPA2 there two outlets, but they are attached to the Lift mechanism. With the magnetic base the only change is the rollers - they can be altered to fit the tank size. The CPE won't take the 3000 series tanks, as they require the Lift.

This manual might help:
 
Although I use the ATL1000/1500 processors I know little about the smaller units. Mine are all geared lid drums. The manual will certainly help. I am thinking of closing the darkroom down in the UK (but keeping the one in Germany) and will be looking to get rid of the processor so before you invest too much in the CPE2 or buy a lift get in touch. And if you can squeeze a DeVere 504 in, let me know! ;)
