Hey Blakout,
Check out Andrews Comms here
http://www.andrewscom.com.au/site-section-10.htm
On the Skywatcher page, Skywatcher Plossls are at the bottom of the page and are $29 each. Quite acceptable eyepieces, good bang for your buck. Nearest size is 12.5mm or 17mm, also on the Guan Sheng page is a 15mm for $29 also, the Andrews ED ones are quite special too, I have two of these ED ones and use them all the time.
Cheers
Chris
