I have several now:
ASAQ - Pure and most expensive:
Jasmine by Abdul Samad Al Qurashi 3ml Perfume Oil Attar | eBay
PPG - Cheap and effective, not convinced about purity though:
NIGHT JASMINE GORGEOUS ROLL ON NEW PERFUME OIL ROLLER 3ML | eBay (http://www.ebay.co.uk/itm/371355468608?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT)
Not got properly started with this one yet:
Jasmin by Swiss Arabian 3ml Perfume Oil Attar | eBay
And I have a Malaysian Jasmine oil on its way - but that could be a few more weeks.
