The fully coated but not multicoated Sirius Ploessls are acceptable, if not outstanding, eyepieces. The Tele Vue Ploessls are clearly superior as are Masuyama based five lens element designs such as the Orion Ultrascopics and the Celestron Ultimas.
As with all Ploessls, an to a somewhat lesser extent with orthoscopics, eye relief becomes quite tight in the shorter focal lengths. Barlowing a longer focal length may prove a lot more comfortable.
Here's a review that included the 17 and 20mm Sirius oculars.
The Burgess Optical/TMB Planetary Eyepieces are very good buys if you're looking for short focal length eyepieces with long eye relief.
