I don't know of any complete systems for under a grand or even if I would trust one for under that either. You could probably find someone to sell you a head unit or maybe find someone really needing the cash and willing to depart with their kit for that price. Although, I would really question it if they were willing to sell it for that price.
What sounds best for you is the Kenne Bell 1.5 kit. It is a very easy kit to install and low maintanence. With just this charger, gears, TB, mass air meter, I was able to get an extra 110 HP on my 95. The price though for a new one is around 2 grand. Kenne Bell is beginning to put together a website but it is not completely online yet. You can access it here

I hope this helps some.
