The only sites (besides the one above which looks like a great start) I can see with STF info is http://www.stcarchiv.de/stf.php
, but they are both pretty sparse. LGD has the STF game reviews here: http://www.atari.st/listmagazines.php?magid=1
I'll keep my eye out for some fairly priced, good condition collections on ebay. Ideally I'd like to see them available in formats, HTMLised with all the pertinent info as above is great, but I'd still like to see complete issues with adverts in PDF format.
