Yes I have tried rksons and thought it was great, slight variations from batch to batch but really nice. AGARWOOD Indonesia ( Muhammad T.) has some great indo sandalwood oil at around $2500 a kg and he is reputable as I have worked on a project in the past with him with outstanding results.Some smell better than the others. Like RK sons has a sour scent in the opening, I do not like, bt few minutes after its smells the way I like it.
I did the same Ejay. Bought some and buying more and stashing them away for future. It will age, I dont have to deal with higher pricing and doubtful qualities I am thinking.
