Just to clarify, tell us a little bit more about your background experience. Will this be your first mount and telescope, or have you been observing visually for a while. If you know your way around the sky and a German Equatorial mount, then I agree with the majority opinion, your money would be better spent on a used Sirius or Atlas mount. For astrophotography/astrovideo those are really just great places to start. Been around for a while and good value for their cost. I like Losmandy very much(I have several of their mounts) but I started with an Atlas that I used for 7-8 years or more and learned enough to feel that a step up in performance was warranted.
On the other hand, if you are just getting started, an AVX could be a nice introduction to the whole field. There are a lot of basics to learn with respect to using a mount, that you can learn with the AVX. You can probably get a number of years of use before you grow out of it and are ready to graduate to a higher grade mount. No matter WHAT mount you get, I always council PATIENCE. There are A LOT of steps to getting good pictures(and I am still learning most of them:-), and there is ALWAYS something else you can do to make things better. Set small goals each time you go out so you can declare victory. Start imaging with things like the moon and planets, where you are using short exposures so guiding and tracking is not as critical. Then move to bright Deep Sky Objects like the Pleiades and Orion Nebula. Add complexity to your set up step by step. And most of all, remember to have fun!
I'm just getting started with astronomy in general, I've got my 8" SCT on Alt-Az on Christmas, but quickly figured it won't be the best place to start with astrophotography. I've never even seen EQ mounts in my life so it's very hard for me to make a decision.
