No one should be afraid to buy Ketron keyboards / modules - they are among the best sounding on the market and have a good operating system (once you get used to a slightly different way of working). I have used an MS 40 for many years and it has been totally reliable and still sounds quite good.

Ketron have 2 main obstacles regarding the SD5 & SD3 module (which is exactly the same keyboard)
1 The lack of dealers (in the UK anyway) - there are only 2 companies supplying them, which means having to buy them without trying or hearing them. Few people are willing to buy on this basis. I like to try it, put my cash on the counter and walk out of the shop with it under my arm.
2 This particular keyboard is very competetively priced in it's basic form (£1300 for the SD3 at BCK) but has no "USB to device" to enable use of a Thumb Drive - nothing but a floppy drive to "save to" / "load from" unless one buys the Hard Drive model which costs £250 more.
£250 for a smallish (in todays terms) Hard Drive is daylight robbery. I want an SD3 myself but am not willing to depend solely on a floppy drive and certainly not willing to pay £250 more for the HD version. If Ketron get their act together, these kb's should sell like hot cakes.
