If you ensure that the controller you get is class compliant you won't have any worries with drivers, or keeping up to date with Logic. As they will be able to transmit MIDI MMC/CC messages which Logic can deal with.
In the past i was always a big Novation fan, and loved the Fatar based SL controllers - they could automap, integrate and display parameters on their small screens - and were great. However, i had an issue with their automap software and was forced to remove it (You basically had to wrap plugins with it to get the 'deep' integration), that in turn then caused Logic to fail to load years of saved projects (Basically as it couldn't find the automap wrapped plugins).
You can imagine the Shock and horror! I could never comfortably use Automap anymore, as great as it could be, i didn't like holding my projects to ransom like that and so swore to never use anything as invasive - So be wary of such products and their pitfalls, Akai do something similar.
I then jumped on to the Nektar Panorama (61 key), and that's a great controller, it integrates as deep as automap, shows parameters on screen but doesn't rely on anything going in to your projects, or Logic as a whole. However.. Again the keys aren't what you're looking for, nor is it large enough - And who knows how long Logic will be supported with it?
I went through a period thinking that if i got the right controller i could actually program entire virtual synth presets from scratch, and would be able to offload some of my hardware. But in reality that idea will never be realised, so i've relaxed on that a bit now and went back to basics.
So, you need to really think what you want to control, while mixer support sounds nice, it only truly works if you're using powered faders - without that it's just a confusing mess and really fiddly.
Likewise if you're wanting a ton of controls thinking that's going to give you everything at your hands - sometimes it can be overwhelming, and just simpler to have 8 endless knobs and set them up via smart controls on a per instrument/preset basis.
Not sure where i'm heading with this post, but as someone who's bought and sold a lot of hardware to get to where i want to be, you have to make sure you get what fits and suits you, and not just what's available out there - and certainly don't necessary go with the sea of user reviews because 9 times out of 10 i wish i went with my heart initially and not my brain (Particularly after researching online).
For example, using your Casio with something like the Nektar Panorama P1 by the side could an option if you enjoy the Casio and wanted to bring a controller with display next to you for the plugin parameters. But then it may be too goofy for you to setup like that and you want an all-in-one solution.
Me personally i'm most comfortable with a 'dumb' 88 Key for playing, and an old Mackie MCU on the side for plugin control, i love it! In fact, unlike most Mackie users i barely use it for mixing, but rather plugin/eq control - i just like to have a screen feedback when i'm moving controls, it's a really important factor for me.
Gonna stop rambling now, as i'm really not sure where this post is heading, i think i have an unhealthy controller lust! lol. Hope you get to try them out, The large keylab is very good, and used with Analog Lab is really fantastic, and your heart is halfway there.
