Pioneer DVD: 115 (w/ tray) or 106s (w/ slot)?

I'm looking at DVD players for the new system I'll be building soon, and I've pretty much narrowed it down to two drives, both by Pioneer, the DVD-115 which loads via a tray and lacks a digital audio connection and the DVD-106s which loads via slot and has the digital connection.

I have a few questions:
1. Which is faster?
2. Which is quieter?
3. Which is easier on the DVD's (I'm afraid of scratching DVD's if I use the slot-loading device).
4. What exactly does the digital audio connection let me do? I'm planning on having a Hercules Game Theater XP card with Klipsch Promedia 4.1 speakers, so will I want the digital connection?

Thanks!

1. Same speed
2. About the same
3. I guess the slot loader would be slightly easier.
4. It lets you connect the digital sound from the DVD player directly to your sound card and out through your digital out port to your digital speakers. Since you have the klipsch speakers which aren't digital, you have no need for the digital out right now.

Another computer wanted. Donations accepted. :^)

The Hollywood -something- the cheap one... I forget the exact name... is cheap and works fine.
