three things
- do you have a budget in mind $$ per eyepiece. $100, $300 or $500
- do you have tracking
- are you getting a good handle on knowing what is a bad seeing night and what is a good seeing night?
There is currently a great thread (

That outlines the top ones.
I ask #3 mainly that even a great ep will not work wonders if the seeing is bad. There are many factors to take into account. So best to get to a viewing night nearby and look for yourself and then ask someone what their interpretation of the seeing is like.
