The link is expired, but on nicodouga anf youtube there are several karaoke off vocal videos. On nicovideo they are labeled ニコカラ and on youtube some off vocals are also labeled that way. You may want to click through some of those, and if it seems high quality enough, you can use that. (Most of those videos probably use the original off vocal provided by papiyon anyway?
