Alright, I'll help out the hotster, but he better be willing to clean my place up every other day and do my laundry.
Look hotflaps, you have to know what the Christ you're doing before you know what to buy. Otherwise you're going to wind up buying a goddamned chainsaw when all you need is a freakin' can opener.
After listening to that "Let it Rain" demo you posted, my first recommendation would be to get yourself some singing lessons -- like fast. Seriously. My dog still won't forgive me for playing that one.
Second, find someone who knows what the hell they're doing, whom you can also trust, and ask them what you need. This means you have to use your skill of making friends. I suppose anyone can do that, but keep in mind that friends don't like it when people ask them to do everything but wipe their ass for them . . . so this might present a challenge for you. You also have to use your listening skills in order to absorb and comprehend the advice they give you. This could possibly pose a whole extra set of challenges for you, I'm guessing.
Also, if you plan on keeping this person as your friend/ally,
don't play that Rain song for them. I'm not going in to reasons right now, just trust me on this one.
Once you know what you need, read some product reviews and come to places like this and do a KEYWORD SEARCH to get some opinions on it. Once you feel confident about it, use your best judgement and take the plunge.
