I recently came across this on youtube and wanted to share.

I have been on the hunt to search for relatively cheap macro pads. But this looks like a good idea for those who want the features but not the premium of a high end Elgato device
Do yall have any Macro Pads yall recommend?
EDIT:
Since we are talking about Macropads. I also found this,
I have a macro keyboard that I use called a Koolertron. It doesnât have screens so its not a Stream Deck alternative but where it lacks in screens it makes up for in the amount of keys there are. 
48 Keys with 4 Profiles to switch through = 188 Keys! (1 used for switching so 47*4)
How do you keep track of all the Marcos you set? that is an insane amount of options
it totally is and itâs actually more because of how I set it up.
I setup the keyboard to use really REALLY weird shortcuts that are in conflict with nothing ever like Super+Shift+F1 or some other nonsense. This allows me to assign these weird keys to specific application functions and then I just change my mindset based on what app I am using at the time.
So how exactly do I keep track? I have no idea . . . I just do. I suppose its a really weird talent because I just remember what key does what in whatever app I am in. I also have different sets of keys in OBS depending on the show or video I am recording so I can switch between those show sets mentally somehow. Of course, if youâve listened to DL for more than 2 episodes you know how complex my OBS setup is. lol
I keep track just naturally apparently. I even sometimes change what keys do what function right before recording and I transition fairly seamlessly. I donât know how that remotely works but somehow I can do it.
I do think there is some benefit that I use that keyboard every day at least some so maybe I just kind of trained myself to do this stuff.
This is an approach that I would agree with, My original plan was trying to use keys that donât exists physically, like F13-24 or a combination of them, If My math is correct combining these in pairs of 5 (f13+f15+f20+f22+f21) would allow for 462 âbuttonsâ to exist.
If I had to guess, Probably because you set it up manually instead of âLearningâ
I just donât know how to do that so I didnât bother learning how to do that lol
Depending on your system, you likely canât do that. KDE doesnât accept anything as modifiers other than the normal modifier keys. Though Super+F42 could theoretically work. 
Well I guess kind of. I have absolutely no clue, not even in the slightest, which key does which weird shortcut combo. I only remember which key does the specific function that I need to do.
I think maybe itâs because I set it up manually but I also set them up in patterns and Iâve likely used each key hundreds of times for those functions. I think at this point I trained myself to be very adaptable to this workflow though I dont remember a time where I had any issues with it even when I first implemented it over a year ago. Zeb and Ryan always refused to believe me that I just remember it but it is what it is.
LOL! Looking at @MichaelTunnell 's blank keypad just makes me think of those Original StarTrek episodes with the âcomputersâ being just these big panels of un-labled blinking lights.
Did those key caps come in white-black colors in a 4x4 grid pattern, or did you arrange them that way? Whereâs the red âPanicâ key?
the pattern showed in the image is the default pattern and I never changed it.
Get a Cherry MX under there and you could do active sitting.
