Thanks for the comments guys.
What would the reason be to not mix Active and Passive humidification systems? Maybe because they kindof work against each other (One humidifying, the other de-humidifying)? I was mostly thinking about doing something like set the Avallo to say 63% and have the beads at 65%. This way the Avallo prevents drops and the beads prevent spikes. Kindof like an HVAC system in the house keeping the temp between 65-70. AC kicks on if temp goes over 70, Heater kicks on if under 65.
Any suggestions where to look for New/Used Thermoelectric units? I looked around a bit and found some suppliers, but it looks like there are all kinds of different systems out there. Not sure exactly what I need.
