Not that I have seen Bruce (apart from a national geographic one at Toyworld) You are best to do what I did and go through a proper telescope shop like Bintel, Astro Optical Supplies, etc. They will all be able to advise what is best for your budget and needs and freight it to you.

I've seen quite a bit of difference in pricing between some of them for a few items lately. Do they tend to match prices when asked or are they pretty inflexible?
