aiya if u want to test the h1 or maybe even the h1d with the imacon digital back, u can go over to prophoto in plaza sing.or if u are really determined, why not go down to shriro house and look for the sale rept there?im sure they are more than happy to do demos for u.or if u are too lazy to do so, call them, they do house demo~
by the way the imacon digital back comes attached with a 40g hardrive, so its more convenient than having 10 pcs or more of 4g cf cards if u use other backs.
its a hefty investment,and depending on your passion and work requirment, i would be a worthwhile one.
try to before u decide which one to buy, cause its not a $40 or even $4000
