I think that guy did a great custom job, especially considering the cost.

I have a 2000 Tiburon. It had a double-din (with rounded corners; I love my dremil). I have my empeg running into the aux-in on my head-unit. The head-unit goes into a four-channel amp. When I got the empeg I didn't have the amp, so I used the Pioneer's build in. I've come to like my AM/FM, CD; even though I hardly use it. It is starting to go out, so I was looking at something to replace it and I found the Pioneer AVIC-N2. I know your car only has a 1.5 din, but it may be easier to add 0.5 din to the current hole than add the space for an LCD.
