N-Series 824 vs. S-series

Have a possible customer that needs a new phone system. Right now they use PTSN lines for their 4 line telephones(no phone system). They only have about 15 employees.  So the question is what system to sell them.  N824 or S20 or 50.  They are going to continue using those PTSN lines.  Also what phones can you use on the N series system. I know it's analog, but specific models. 

Thanks for your time.
