Thanks for all the comments and suggestions, so we have:
Burgess Planetary - 60deg - $139
Orion Stratus - 68deg - $159
Pentax XF - 60deg - $215
TV Radian - 60deg - $310
I also found this thread:

So assuming that I can't afford the Radian (I thought there was a 8mm Nagler - but I appear to be mistaken) in the near future, I'm thinking the 8.5 mm Pentax XF will probably be the one I look for, now anyone know of one going second-hand for near charity prices?
PS My dob is f5, so the Stratus may be marginal anyway?
