Ah I have some bad news. After doing some research on Miele last night and finding out he now DJs under the name 'RivaStarr' I found his twitter account and asked him about 'Flux', anyways he replied to me this morning.
Something you probably already knew anyway but I thought I'd ask the guy himself in case he could help out.
So yeah your best bet now is either finding a private collector of his work, browsing multiple record and CD stores (charity shops too) and hoping that you find a copy of it, or, your best bet as you've found out is Ebay. If I had a friend in Italy then I'd get someone to buy it and ship it to you but alas I do not.
Don't give up hope though, it'll pop up somewhere, someday.
