Need to Keep one OPL card

[Great Hierophant]

I have a lot of sound cards I intend to put up for auction in the next couple of days. Unfortunately, I would still like to have a card with true Yamaha OPL functionality. Here is the list of cards I am planning to auction:

Sound Blaster 1.5 CT-1320U w/ CMS
Sound Blaster 2.0 CT-1330 w/t CMS
Sound Blaster Pro 1.0 CT-1330
Sound Blaster Pro 2.0 CT-1600
Sound Blaster 16 CT-1750 MCD ASP w/DSP 4.05
Sound Blaster AWE32 CT-2760
Pro Audio Spectrum 650-0002-01
Adlib Music Synthesizer Card

I can only keep one, which I intend to use for the odd game, but which one should I keep.

I also intend to auction the following, so keep you eyes peeled on eBay:
Gravis Ultrasound ACE w/1MB
IBM Music Feature Card w/Midi breakout box

This thread has been cross-posted on several boards to obtain the maximum number of opinions on this subject.

Here are the eBay auctions I am currently running. http://search.ebay.com/_W0QQsassZgreat_hierophant

The one you keep depends on what you plan to use it for. If you play mostly 386/486 games, keep the SBawe32. If older, keep the SB 1.5.

For right now, I am keeping the 16 and the ACE. I am auctioning off the PnP and AWE64 Gold instead. Both are redundant and a pain to set up, (I hate ISA Plug and Play.) I may not even keep the ACE, but it is the easiest to set up of that lot.

I am in the hunt for an SB 32 CT-3600 with a real Yamaha OPL chip. Most have Creative CQM chips, which are inferior.

I am also auctioning off most of my video cards too, keeping only an IBM CGA for myself.
