Can you only get the whole series on DVD via eBay? I've got some old skool VHS videotapes of episodes but that's about it. To have all the series on DVD would be a weekend well spent! Dai-X was pretty cool though - in fact, a lot of the design in the series was great. The X Bomber is another favourite of mine!
'tis a long time since I was last commenting on this piece but it occurred to me that you'd be pleased to know of the availability of an official DVD set of the whole series plus plenty of bonus stuffs (although I won't be surprised if you already know of it and own it by now ^.~ ) readily available from places like play.com ^_^
Yep - there's no current official release of the series (I hear the english-dubbed master copies no longer exist) so evilbay is the only way (I'm such a poet *^.^*)... or free copies from fellow fans ^_~
