got reply. ... www.donberg.de says they cannot deliver 6582A.
funnily, www.donberg.ie wrote that they don't have stock on 6581R4AR BUT they quote a re-order time for 10 days. unfortunately the price for 6581R4AR is much higher than for 6582A. but first, lets see if they can really deliver. i am still not believing it... :)
so i wrote donberg.ie today if they could also order 6582A , waiting for reply ...
meanwhile i've managed to get a couple of SIDs from ebay though, and from other (austrian) fleamarkets within 48 hours from damaged, working, or partially working C64/C128:
1x 6581 CBM 4684 (inside C64 breadbox, fleamarket)
1x 6581 CBM 4283 (inside C64 breadbox, fleamarket)
1x 6581 (only the chip, via ebay germany)
1x 6581 not delivered yet, inside a C64 ebay breadbox
1x 6581R4AR (only the chip from a C128, from ebay)
1x -"- (?), from C128, fleamarket, not delivered yet
1x 8580R5 1489 25 (C64C, fleamarket)
1x 8580R5 (ebay)
1x C64C (yet unopened)
1x C64C (yet unopened)
seems like there still are people who are happy to get rid off their old C64 and C128's. but, crazy hell, some really want up to 180 euro (which i did NOT buy), one c64 i got for 13 euro ...
i think if you are lucky, there are still quite some c64 around. at least in austria + germany. but definately you will have to pay a couple of bucks for them :-/
