For the price I think the vertex is not bad considering your getting the TDS monitor, back flush feature and a pressure pump (most often are cost extra add-ons).
You can't really compare it to a $90 RO only unit because with the pressure pump your going to get more production from that unit.
I have an Aqua Safe unit and I like it but I think they have gone out of business.
Cheers,
Vic
