If you are buying think through whether you want a wider field of view (S30 series) or more details (S50 series). S30 might be a better bet for amateur viewing.
Saying all that to expand on how the wide field or not is an important decision. If you primarily think of a telescope giving detailed magnified views of the moon or similar, then you will not be happy with a wide field regardless of how powerful of an eyepiece you use.
On a side note, I have an 8'' dobsonian and people think I might be getting magnified views of DSOs with that by default. I have to explain about eyepieces to them to clear that out.
