Thanks to everybody on here for the advice
I decided to just get the Celestron zoom eyepiece thingy, about $90 off of eBay.
I don't really have a set budget at the moment for more eyepieces. I think I will pick them up as time goes by, & I get a better idea of what I want or need.
I still need to look further into the difference between 1.25"& 2" eyepieces. I would have assumed that they are just different form factors, but I suspect I may be wrong.
Still learning little bits as I go
Thanks again, IIS
