Welcome Craig. You will get plenty of advice regarding eyepieces from more experienced members than me. The range is almost unlimited, from $50 plossols to $900 Ethos and plenty inbetween. Together with buying new eyepieces consider purchasing a Telrad, it really makes finding objects easier. Also a couple of software freebees, Stellarium and Tonight Sky Planner. I find both essential to assist and plan observing sessions.
Good luck.
Rod
