AFAIK, this is the place to check the price of Japanese astro gear:
http://www.rakuten.co.jp/
It's all in Japanese but the search works if you know what to look for.
Takahashi FS102 $AU2300
Pentax XW $AU320
Vixen LV $AU120
Vixen LVW $AU210
and
Vixen Porta + 130mm Newt $AU480, so $700 locally is not so bad I guess...
