That is a really hard 45 to come by clean. Especially with the PS. It sold practically nothing upon it's release and is almost impossible to find in clean condition. The number of collectors with this on their want list far outnumbers the copies available. Be prepared for a nasty conversion rate since the USD is funny money up here in the Arctic Circle for the time being. Not very tempting to sell anything priced in USD.
A friend of mine who's been in the Norwegian beat collector loop for close to 30 years says it'll easily fetch $900-1000+ locally if a M-/M- should magically appear.
The 2 times I've held one in my hands they've both been VG'ish with photocopied sleeves and no original centre.
