Used UA-5 $200 if you're patient. You may have to do the digi-mod yourself.
Make your own mic cables from Markertek $40
I'm not sure what you would need to go into a D8 from the UA-5
Light Stand - $55, this is the one I have. I have yet to actually run it but it feels nice and solid. You will more than likely need to buy a 3/8" to 5/8" adapter for $5.
$300 for all of that.
I spent $200 for new Shure vert bar, mounts, and windscreens. That's a little overboard. You could do well with
AKG t-bar $25
Shock Mount OptionsWindscreen OptionsYou will then obviously need mics, and that should round out your package. You may be able to find AKG 391's for around $500. AKG 481's can be had for around $800 but that would put you out of your price range. There's also
Core Sound Studio Projects C4's (I think I got that right) - $300 for a new matched pair. Do a search for superlux, they go for around $200 new with a bar, windscreens, and mounts included. I don't think anyone has had anything bad to say about them.
One last thing. You will need battery power for your UA-5. I got two 3000 mah batts with smart charger from batterspace for $60 (I think-check my post in the power forum), and the parts for the DIY power cable (archive section) are about $20 at radio shack.
