Dogs on Acid has an MP3 store with most of RAM's back catalogue (including other artists signed to the RAM Records label) http://downloads.dogsonacid.com/recordlabel/102334/ram-records.html - try that if you're having trouble finding their tunes.
Let's face it, Andy C and Shimon dominated DnB in the old days. They deserve much much much respect.
I've got most of the Ram releases on vinyl and wouldn't sell them for love nor money.
Good luck hunting them down! Rarer than rocking horse-shit now! Although Ram is celebrating 15 years so they are repressing 15 of their classic anthems... only 1500 copies each! Get 'em quick!
