An Agent Controller on a Budget
Slam Buttons at $29 is the cheapest thing we sell that is genuinely a controller: two large round red arcade buttons on a cream plate, cable out of the top. For most people it is also the last one they need. This page is the whole ladder, from spending nothing at all to spending more than the job requires, with what each rung actually buys.
Can I do this for nothing?
Often, yes, and you should try. Your terminal, your editor and your agent all let you set key bindings, and a free remapping utility can turn a key you never press into the one you press most. Caps Lock is the usual candidate. Spend twenty minutes there first. If that removes the annoyance, you are finished, and you have saved yourself the money and the wait for delivery. We would rather tell you that than sell you a box.
What does $29 buy that free does not?
A target you cannot miss. The argument for two big arcade buttons is not that they send something a key cannot send, it is that they are large enough to hit without looking and satisfying enough that you actually use them. Accept on one, reject on the other. Everything more expensive in this category is a more elegant way of doing what those two do. They are loud, which is either the appeal or the reason to buy something else.
What about the $19 one?
The Keycap Fidget at $19 is our cheapest object and we should be straight about it: three keycaps stepped diagonally on a clear base, each printed with a different AI tool's mark. It does not plug into anything and it does not send anything. It is a desk object and a good small gift. Buy it because you like looking at it, not because you expect it to control an agent.
Where does the money go above $29?
Into key count, knobs and materials, not into capability. The Left-Hand Pad at $49 is twelve keys in four columns of three with two rotary knobs. Vibe Pad at $59 is three keys with a clip-on microphone, for people who would rather speak the prompt than type it. Pedal Three at $69 moves three actions to your foot. EM Mini Pad at $75 is five keys and a knurled knob in a small, heavy aluminium block that also runs over Bluetooth. Every one of them sends key presses, exactly like the $29 pair. Pay more when you want more keys, a knob, or an object you enjoy owning, and be honest with yourself about which of those three it is.
What is the most expensive mistake?
Buying the most capable thing first. Sixteen keys is a pleasure if you have sixteen things to press and a waste of desk if you have three. The same goes for four pedals when two decisions is the whole of your review loop. Count what you repeat, buy for that count, and give yourself permission to stay at the bottom of the range. Nothing here gets better at its job by costing more.
