I agree with the others that you have no gap between your 14mm and your 22mm. On the low power end I would consider the 27 Pan and the 28mm UWAN (William Optics). If you can wait about 2 months I would seriously consider a 30mm Orion Stratus, too!! They're scheduled to arrive in July. The 30mm Stratus will sell for $180 (US) and the 35mm will sell for $200 (US). I just reviewed what appears to be a prototype for the 35mm Stratus. The prototype is a very remarkable eyepiece and bodes well for the new low power Stratuses. That review is here:
