Seconding the ubiquiti comment. Buy used parts on ebay (except the NVR, a somewhat recent update sunsetted the old system) like switches, USG, WAP…buy used if you can. Ubiquiti stuff is well built, at least “prosumer” quality if not better. New stuff is really pricey, and I bought new initially, but recently added on to our network and bought all ebay stuff for 1/3 the price.
