I did purchase the ISonics machine from Amazon. It seems to clean okay, but the heater doesn't work. After 30 minutes, the water was still room temp. Most likely it was damaged in shipment, as the box was totally and completely trashed when it arrived. Sending it back, I'll probably order another one later. Maybe from a different vendor this time!
BTW, for those of you who owe the ISonics, do you find the records are still fairly damp when the drying cycle is over? The cloth was needed, but it only picked up a little moisture, the records are not completely dry. If this is normal, then I'll need more drying cloths, as one is not enough for a big cleaning session.
