Diki I dont think its a fragile unit in fact it looks very quality built...I was able to put my finger under the keys to give it the "FRAN" test & the keys are solid.....but I think its more of a why take a chance with only one UNIT in the country more then anything else. It sounds very live but not much different then the SD1+ I had or SD5 riffs of what I heard....I hope theres more lurking inside to blow us away.
