It's like anything...you get what you pay for. Can you afford a TeleVue? Me neither, that's why I drive a Ford when I'd rather have a Cadillac. (Not really but it sounded good!) For me, the price difference between "designer" & "generic" EP's isn't worth it. They both get from point A to B. The difference I've noticed is mostly around the edges of the Field of View. If your trying to view planets your probably not going to be concerned with the wide-angle EP's. (Oh, if your main concern for the new 'scope is planets, you should have plenty of time before making a purchase. Jupiter is getting too low for really good viewing and that's about it for a couple more months at least). Any Sirius Plossl should do you fine. I have an "ED" EP that is ok. It puts a nice color to Jupiter and Saturn: one that's not quite so bright and is pleasing to the eye. As I've said, I'm a huge fan of Orion (the constellation too!) and I only have Orion EP's. So, I might be biased. I've seen through some Antares EP's which were also nice. Other then that, only TeleVue's that belonged to Thom. My favorite for the planets (Jupiter and Saturn) is an Orion Highlight Series 7.5mm EP. My most used is the Expanse Series 20mm.<br /><br />At one point I thought high power EP's are what I wanted. As time has gone by I've realized most of the objects available to a something like a 10" 'scope and below are best viewed at normal to wide-angle. Very few objects can take high power and anything more then a 15mm is beyond the focusing ability of most focusers and require nearly perfect sky conditions. Those EP's will hardly ever get used unless your really into the Moon or splitting double stars. That's my 2 cents worth...<br /><br />Your welcome for the input, hope it helps some.
