I think whatever name you want and suits your little guy is best, whether it's something you thought up or if it was suggested. I struggled to come up with Merlin for mine, but I'm happy with it, even if I get some weird looks for it haha. As for the mister, I would highly suggest waiting until you can get a good mist system over a Monsoon. I've only heard bad things about them on here. For what it's worth, I just looked them up and amazon had them at $80. I paid $100 for my mist king. For $20, just wait until you can get Mist king. I know there is another good quality mist system out now, just drawing a blank on the name. Maybe someone will chime in, but I really think you'll be much happier if you hold off from the Monsoon until the funds are there to get a high quality system. If nothing else, having a 5 gallon reserve of water is really nice and I can put a tank heater in the bucket so that the water isn't so cold coming out of the nozzle.
Good luck and welcome!!!
