When I bought my 10" Dob, I invested in the Meade Series 5000 Plossl Eyepiece Set
http://www.staroptics.com.au/catalog...ge.php?pID=126http://www.meade.com/series5000/index.html#eyepiecesets - the 5 element set. I also picked up a 3x barlow and a set of filters. Seems to cover most situations, although I was suprised I do not seem to be able to get close enough to see the GRS even with my 5.5 or my 14mm with barlow combo on my 10" Dob. Nice views, but I have found myself far more fascinated with deep sky viewing as planetary seems a little dissapointing. I suppose with the incredible images on the net, one gets a tad spoilt. The Meade EP's do offer better viewing than the standard EP's that came with my Celestron, and Dob. For me, I'd like to investigate the 2" series for the deep sky stuff a little closer. It seems to offer the best deep sky fields. Sadly, the classifieds have not been over run with such items for sale lately. I guess what you want to look at might play a role in your choice as well.
