Hey,
I'm with them, they supplied me with a TP Link TL-WR840N - not a great piece of kit but it works.
I use the TP Link as a backup (to keep the Mrs happy) when I take my UniFi AP AC Lite to clients and that works ok.
IMO it's worth the spend on the UniFi units... there's just a shortage of them in SA at the moment until beg/mid Jan
