Do you need to get rid of these so quickly? These items are not in high demand so you need to wait for the right buyer to see your ad.
The ATR8000 should be saved if possible - if you are going to throw it away Id be happy to make it worth your while to ship it to me. I dont have any interest in using it but Im sure at some point the right buyer would be ready to take it and make use of it. Just my $0.02
The 1050's I think are a harder sell since many are moving to other storage means like AVG, SDRIVE, etc...
