Ditto on the fan. I purchased a smiliar one at Walmart. It resides in my keyboard bag beside the S900. As for speakers, I used internal speakers for most of my nursing home gigs until last fall. Since then, I have got in the habit of taking one (I own a pair for larger gigs) of my Eon 15 G2's. I leave the keyboard volume for the internal speakers about where I normally did, tilt the Eon up beside me, and bring the volume up to where I can just hear it a little. Adds a whole new dimension to the sound, and I am still retaining at least some of the stereo separation from the internal speakers, to satisfy my ear at least. I also have a pair of Roland KC100's which I never use. Just don't care for the sound. I am however, loving all the posts on this topic, as I am really in the mood to try something different. Gary
