Hmmm, I would want to go with a known manufacturer. Also look for something well made and not overly complicated. The ability to get parts readily and customer service is nice

. Especially with a system that big

. It will take some effort and dedication so the more dependable the equipment is the easier and cheaper to maintain. May take some patience to get just the right parts but you can do it. With the system you are planning, you will want every dollar you can get! May as well make any purchase from here on out aimed at that bigger system

. It will be cheaper in the long run, I can quarantee there will be some cost you arent aware of

.
