Blu-Ray + laptop

[Vermin]

Hello. We have a Full-HD laptop (well, actually it's called Full-HD because it has the right hardware to play 1080p movies and it has a HD-DVD player build in) and we want it to be really Full-HD. What I mean is getting a Blu-Ray player (or burner) for it. But those FireWire/USB players are very expensive, most are even more expensive than a PlayStation 3 (I dunno why, you can do more with a PlayStation), but we want it much cheaper than a PlayStation. The only cheaper players I can find have SATA connection. Is there someway to connect a SATA Blu-Ray player to our laptop?

By the way, we have USB 2.0 and 4-pin FireWire S400, so we might buy some sort of SATA->USB connector, but we don't know if USB 2.0 or FireWire are fast enough for Blu-Ray.

EDIT: I found some kinda cases I can use to connect SATA to USB 2.0 or FireWire. So again, are USB 2.0 or 4-pin FireWire S400 fast enough for a Blu-Ray player?

Seeing as the Xbox 360 ran an HD-DVD off firewire, I'd believe it would be fast enough on PC as well. However, I'd still find alternatives.

There are some cards that allow for external SATA drives;

(PC cards are available too, depending on your machine)

You could probably invest in an internal laptop drive as well. I didn't think they were tremendously expensive, but still harder to come by.
