I have a pair of IBM speakers that still sound fantstic despite being so old the plastic has started to yellow.
Bue otherwise no IBM products. Regular keyboards seem loud enough to me, and I can't imagine getting one specially made to make even more noise. Last I checked my typing speed was 60-70wpm on a good day anyways, so it's not like I need the hardware to help me out.
Besides all that a keyboard is almost like a wristwatch: I can't justify ever spending more than $20 on one.
