And for some of us, we were too busy messing with PSX, PS2, gamebox, Xbox, or whatever to notice how awesome the dreamcast really was. It took these deep discounts for me to perk my head up and notice it (I love to bottom-fish for gaming stuff anyway). That, and the VGA output is a really big deal when it comes to cabinets.
I just discovered Bleemcast which says to me that I can now run Playstation Tekken 3 and Gran Tourismo 2 with Dreamcast-ish graphics in VGA on my cabinet. My head is spinning!

I have found several of the emulators (MAME included) to be unimpressive and/or unstable on the DC. The front-ends are typically pretty bad too. I think I'll be sticking with MAME on AMD/Windoze.
For those now building a DC library: check out half.com in their discount section. There are several excellent titles, many new, for well under $5 that ship media-mail for $2.49 and under. I just bought Sega Bass Fishing, Rainbow 6, and Phantasy Star Online for $13 shipped. Avoid the eBay inflated shipping thing. Of course none of those titles are suitable for a cabinet, but my cabinet is also connected to a TV and I have native contollers too...
Time to hack a Sega Fishing Rod into the cab?!

Oh.... you guys who recommended Soul Calibur. THANK YOU! I got it last week and, while I'm not a huge fighter fan, I'm LOVING this game! The only fighters I've played since Mortal Combat for the Genny (which sucked) is Tekken 3 on the PSX and Samurai Showdown (various versions) under MAME. I've got a new favorite that is DEFINITELY going to feature in my cabinet!
I think I'm becoming a DC junkie a few years to late...
