IBM Keyboard

first, you have the beam spring stupidly loud with a solenoid in a lot of them built well and they are ridiculously tall and expensive, then you have the slappy Capacitive driven model F keyboard of what I use a lot of and I have 4 of those if you think the model m is the best-bucking spring then you have not slapped away on and it is a lot smoother and it is louder than the model m, but it's also expensive for a NON-XT layout a model f AT can cost upwards of 500 bucks and an f122 iv seen up to 1k for restored there are other ones like 4704 and those cost a ton for a nonreproduction you can get a reproduction for under 400 bucks. The model F is a literal brick Shithouse rated to 100M+ keystroke life and cant fall apart because of plastic rivets like the model M. The venerable model M what most of us know about is a buckling spring over membrane design vs the capacitive of the model f and comes with 1 plate of steel vs 3 or 2 of the model for all metal in the 4704 for the case the model m is considered to be a tank build keyboard but in fact, it has an Achilles heel the plastic rivets used to hold it together over time pop off and have to be drilled out and replaces with bolts or screws called "bolt modding". but you got to hand it to them these keyboards are around 25-34 for the majority of them and they have held up better than a razer can and can be fixed. side note model m is MEMBRANE diven. still better than a lot of garbage gamer keyboard built well types like a dream
