I've got an odd selection - but that's because i got mine from a mix of places, either being given for free, bought new or second hand. Currently with my F/5 6" i've got a 6mm WO, 9mm unbranded that has a 66˚ field of view, a 17mm celestron plossl (worthless really), a seben 8-24mm zoom (surprisingly good), a 30mm vixen and a x2 barlow unbranded. Honestly, all are great barr the 17mm celestron plossl, it's just such bad quality compared to the others and has awful contrast when viewing. I did buy it second hand off ebay, however. The 6mm WO and 9mm I use for lunar and planetary which are fantastic and give good detail and contrast when barlow'd. The other 8-24mm and 30mm are the low power EP's I use for wide-field. I find the 30mm vixen great and it's really good for the price. The Seben 8-24mm zoom is fantastic until you get close to 8mm or 24mm, with this one i found it's best to stay between 10-20 which gives good contrast and nice stars. I almost always start with this one in the scope, and it's probably the one i use most often. I'm not awfully bothered with great eyepieces, more interested in learning imaging so I suppose great quality, expensive eyepieces would be a waste for me. These ones are a lot better than the stock EP's that come with the scope but not as good as the higher-end, i think they sit nicely in the middle - except the 17mm plossl. i'm not sure why i haven't sold or thrown it out the window.
