Hi there I no longer need my KEM - I'm really happy with CH DT225 trackballs. I'd like to swap it for something else - different trackball (even another DT 225 in any version) or some keyboard - cherry reds maybe? Please let me know if you're interested. Trackball is in decent condition. There is no palm rest (i've never used it and lost it in time) and the primary button has a little darker dot (normal wear i guess). The ball itself was always taken care of - after i've got a dent on the first one i had i really paid attention not to scratch or dent this one and it's indeed super smooth like new. I'll make some pics tomorrow.
