These are excellent eyepieces and only a fraction behind the Pentax XW's, which replaced them in about 2002 or 2003. The Pentax XW's are still current models in all focal lengths. Depending on your scope and personal ability to compensate, the 21mm can have a little field curvature, as does the 20mm Pentax XW. The 7mm Pentax XL is an excellent eyepiece in every respect, in every scope I've used it in.
I would have said $USD 195 is a bit over the odds for these and I wouldn't be paying it.
While neither the XL's or the XW's hang around very long in the classifieds, if you're fast enough and check the classifieds every few hours, you will get an XL in very good condition for between $120 and $170 and an XW for between $190 and $250 in very good condition.
At $140 to $170 these are probably good value, if in excellent condition, otherwise I would be adding a few $$$ and buying XW's on the used market.
