[Waxing_Gibbous (Peter)]

It was in pretty rough shape when I bought it and now its worse so I want to replace the mirror on my 8" f5 GSO Newt. A recoating costs more than a new OEM mirror so I figured I'd split the difference and upgrade a bit - perhaps add a better cell. Outfits like Zambuto or Royce are a tad expensive at US$700-1000 and OOUK has a dodgy rep for their scope assemblies, though I don't know about their mirrors.
Any suggestions on where one can get a 1/6 + wave for around 500-700 AU$? Used is OK.
Thanks,
Peter
