For me it was CV. Stayed on the lookout for about 4 years. Met someone who had one but said they were not ready to sell. I just contacted them about every 2 months for over a year and they finally decided to sell. I had to sell my only NIB purchase(BDK) to raise money for CV and I have never regretted it. I recently began to tire of CV, so I made it much harder and now I'm interested in it all over again!
