I found that OPTCORP had both the 1.25" 20mm and 6.7mm in stock for $99 each + postage = $255 USD ($275AU). Any concerns with this choice?
Thanks again for the advice.

For deep sky observing in my 8" f/5 Newtonian my most used eyepieces are a 14mm Delos and 10mm Pentax XW. I wouldn't normally use my 6.7mm except on the brightest objects.
Not saying you need a Delos or XW, but a focal length or 9mm or 10mm is probably ideal for globulars while for galaxies I prefer 13mm or 14mm.
There's a good reason the 9mm and 13mm Naglers are so popular for deep sky work.
Explore Scientific also does an 8.8mm eyepiece which is similar to a 9mm Nagler.
