This is what I have, has focal length of 2032mm. Its brand new and I've only used it a couple of times, comes with GPS. If you are in Cali give me a call, I'll give you a deal on it :-)
With this I'm able to see the rings of saturn, I've seen a couple of neat nebulas. The moon looks awesome, so much detail there.
