Unfortunately, most of them are way below the threshold and hence do not count*). If you look at dos1's numbers, you will see that the unit price/number of units sold is not a linear dependency. It's logarithmic. You need 10x more buyers for each €100 drop. There are currently only 26 more votes for €600+ than for €700+, that is not enough to break the bank. The €600 bracket is only applicable if you get 1000+ votes for €600+, not 1000 votes altogether.

*) Me included I'm afraid , but only because the question was, "how much would you be willing to pay", not "how much do you think is a reasonable price is". How much I am willing to pay depends on my personal circumstances much more than on how much the item in question is worth.

About €100 has been mentioned, but I'd leave it to joerg_rw and dos1 to finalize the details.
