Good Value In 2" Eyepiece?

I have only recently upgraded to 2" diagonals in my scopes (a 12" F10 SCT and a 78mm F8 APO Refractor). I am interested in taking advantage of the wider field of views. I am wondering which eyepieces in the longer focal lengths, around a 56mm Plossl or 32 to 40mm wider angles (67 to 70 degree AFV) are better values right now (quality to price) . I am looking in the $100 to $200 range new or used.

Any feedback is appreciated along with your experiences.

Thanks

At 56mm you might start having problems with the central obstruction. Kidney beaning is common with over 40mm.
Siebert makes some in the $139-189 range in his Ultra-Plus series that work well, especially in a f/10 scope.

I like the 1rpd (aka BW-Optik) 30mm UWA. It's less than $100, and works very well in my f/10 SCT. It should work pretty well in your f/8 as well. It is an 80 degree AFOV, 5 element modified Erfle. Light throughput is excellent, and there's no kidney beaning etc. Eye relief is a claimed 20mm, but feels closer to about 15m-17mm (IMO). Field stop is 41mm.

I think this is the best value for money ep available, bar none.

Clear Skies,
