Hmm, that's one cheap mic, considering you don't need a preamp or a USB converter. You should try to suck it up, but I know how it is.
I'll compose some more hints for public consumption tomorrow rather than PM you (I don't mind PM'ing you but why not share eh?). I'm working on my install guide right now, which is likely to benefit more people.
Stay tuned to this space.
OK, here's a hint: print your lines. Practice them. Mark the paper where you want to emphasize, inflect up and down, etc. You can invent your own markup technique.
If you don't have headphones, close one ear so you can better hear your inflection.
OK, that's more than I promised, much more later. I'll be listening to you after all, I don't want you to suck.
