Need Babel compliant, low cost hardware recommendations

     We are replacing an aging, small network of older Ubiquiti devices and looking at Mikrotik replacements.  We want something that will be good for now with the latest Babel-only loads, and hopefully be good for at least several more years.  Hardware replacement of an entire network mesh can get costly so we are looking at the least expensive options; we are considering the HAP aC2 RBD52G, but open to any other ideas.  Also need a replacement for an old Ubiquiti Air Grid 2.4 GHz device for a point-to-point link, again as cost effective as possible but compatible with the latest AREDN loads..
