Houghy,
The Orion Ultrablock is another good option. I have bought many products from Joe O'Neil (O'neil Photo) in Canada over the years, Joe will match the prices offered by Orion on their US website. I think I would be sticking with either the Astronomiks, Lumicon, DGM NPB or the Orion Ultrablock. I have heard mixed reports on some of the Baader DSO filters, some good, some bad and the Celestron DSO filters are fair only IMO. Avoid the Broadband Light Pollution filters for visual astronomy as they do not provide as much benefit as the Narrowband or the OIII filters.
BTW What can you buy the 20mm Pentax XW for new ? I will sell for 85% of the cheapest new price available in Australia. It is in completely unmarked condition, with screw bolt case, lifetime warranty card, manual and packaging box.
