Count me in. Not that I necessarily need one, but it's always good to buy everything that comes out because the stuff tends to disappear quick and terminally, too 
Eric, I assume since there's serious amounts money involved, you need more than just "me too" 
I'm prepared to do a real pre order, aka: take my monies!
If all others who "me too'd" are serious as well, you're all set for the project
Of course Omega.
I will start project as soon as I have money to buy all components (Even If I already have some in stock)
I will ask everyone to send me money with paypal as soon as I'm ready to start to build the cartridge in the factory line ! 
No problem, Paypal is ready to start. Thanks for the cartridge
Hurray... The treshold has been reached easily... And yet more people can listen to a real OPL4
YZI!!! Interested!!! MBWAVE is soo limited.. I'm going to try SOOTSOUND for sure! As long as XM->LTM will convert properly the samples to OPL4 formats
