i found the archos gmini 400 for ~$280 before shipping, which is a good price considering everything it does. i bought mine back then it was $350. but if you're just getting it for portable music (which there are players with better sound quality) and if you find the 400 is much cheaper than the 402, then get the 400 or another dap that concerntrate on audio playing alone. only get the 402 if you really going to use all its features. i 'guess' that the 400 and 402 use a similar sound chip.
also dont get the remote, its hard to navigate, hard to use, and makes high pitch noise. the color screen for this player is important though, i would recommend some pda screen protector.
the 402 is mostly similar the 400, it can do everything the 400 does plus some improvements: higher resolution support for video, now support wmv9 movie, pc autosync, more powerful morphun game engine, take image directly from digital camera.
i use the video feature a lot on the gmini actaully, since my dvd player can't play avi and mpeg. instead of burning them on cdr or dvdr that the player cant even recognize (also save money) i connect the gmini directly to the receiver->tv, and the details and color on it look pretty decent. i doubt many other people do this though, but thats why i like this player.
