There's the Celestron, or the Meade, low-cost route, for less than $50 (especially, if you, like me, happen to have one or two lying around [I have two]).
Or there's the Takahashi route for less than $120 for a relatively High-Zoot version...
OR there's the Baader Ultra-High-Zoot BIG buck 2" version, for those who must have the VERY best (and, based on history, that MIGHT include me)...
So, it depends on your budget...
In MY case, I happen to have a couple Meade multicoated prism diagonals, one of which I've just collimated, so testing will be easy, if I can make the Arizona summer monsoon weather pattern go away for a few days (or, more realistically, I'll probably wait until the end of September, when the momsoon will have blown away for yet another year)...
