I tend to haunt the local kijiji musician's classifieds , and sometimes it pays off . I just picked up two Gibson "New Vintage" straps for $70 . L&M , the local music shop , sell them for $150 each .
Almost brand new , I don't think they've ever been sweaty . Couldn't resist , the seller had two , I bought both .
Nice heavy duty straps , although I do tend to favour fairly light basses .
