I called Aerocon last week. They don't have either the S'Creamer or the RATT works systems. I think the only option for a microhybrid is Eclipse, though they have yet to reply to an email that I wrote on Thursday. For larger stuff, check out HyperTEK at Sunward, but that will require hundreds of dollars of ground equipment.
My S'Creamer was shipped on Saturday. Unfortunately I'm traveling during the second half of this week, so I won't be able to test it until the end of this month.
I should also mention that micro hybrids aren't certified (but the HyperTEK systems are), so you can only fly them by yourself or at TRA launches for experimental motors. I'm planning to mostly use mine for ground testing and to fly it in an Art Applewhite Stealth by myself. That way I can watch the whole flight and recovery shouldn't be a problem.
