As a drum programmer I invested in some of them in the last 10 years, and always try to invest in things I don't have rather than buying more drums during deals
At the moment I still use SD2 as my main drum sampler (would upgrade maybe if Toontrack let me
- New York Studios Vol 1 SDX (GMS kit)
- Metal Foundry SDX (2 Sonor, 2 Tama, 1 DW, 2 Ludwig kits, ranging from bigger old school drums to small octobans)
- Rock! EZX
- Pop! EZX
- Jazz! EZX
- Electronic EZX
- Latin Percussion EZX
- EZD 1 Kit
Then I also have:
- NI Studio Drummer (Pearl, Yamaha, Sonor kit)
- NI Abbey Road 60s (Gretsch, Ludwig kit)
- NI Battery 3 and 4
- NI Drumlab
Plus all the samples included in Kontakt, Sampletank etc, which I usually don't even install with their library.
Among all of those, I never happened to use the NI drums in any project, and I think I could program some very realistic drums with those five kits alone. Never used Drumlab either. Used Battery as special fx only. Not using the EZD Kit anymore, cause its sound has been abused and is too recognizable.
If we add the collection of snares and cymbals included in the two forementioned SDX libraries, that's more than any world class studio could hand to you for recording.
If I had to start back today, I think I could get the job done buying SD3 only, a few specific expansions maybe, no other samplers needed.
What do you have and use the most?
