Thank you, Brandon.
The Epic ED-2 22mm is the only eyepiece that I have from that series. From what I've read here on Cloudy Nights, it was probably the best of the Epics. I bought one years ago and liked it for the relatively wide field (55 deg - well, that was years ago), good color, good contrast, a field that's sharp to the edge and an economical price. Many observers have complained about blackouts / kidney-beaning when using the Epic ED-2s, but I never had this problem with the 22mm. So later when I bought a used Burgess binoviewer and was looking among my eyepieces for those that had binoviewing potential, I chose to buy another Epic ED-2 22mm. I got the second one used, but in like-new condition. My 10" f4.8 Newt requires a 1.9x or 3x OCA to come to focus with the binoviewer, so the effective focal length of the ED-2 22mm is about 11.6mm and 7.3mm, yielding 104x and 164x respectively.
I can't vouch for others in the Epic line, but the 22mm is excellent for binoviewing, and does especially well on Jupiter. If any of my other eyepieces performed as well in this niche - including a Vixen LVW 8mm and a Meade 5k UWA 6.7mm - I would be observing Jupiter with them instead of a pair of binoviewed ED-2s. I've put together a number of other eyepiece pairs, but none have shown me as much detail with as much contrast as the 22mm Epic, not even my BGO 9mms. I try not to prejudge equipment according to how much I - or anyone else - paid for it. The Epic ED-2 22mms were pretty cheap but they are real good binoviewing Jupiter through my 10" f4.8 Newt. It is what it is. They do get'er done.
Now, if you don't plan on getting a binoviewer, I'm not sure if the Epic ED-2 22mm would work as well for you. If your 10" has a 1200mm focal length like mine, that would only give you about 55x. I'm a big advocate of using lower power to observe Jupiter, but 55x is too low by at least half even for me. So you would need to Barlow the 22mm to get 110x or more. I couldn't guarantee that you'd get the same results as binoviewing the 22mms. You probably wouldn't, although it'd still give you a nice view of Jupiter, I have no doubt.
