Unfortunately, I have no idea what other products in that price range would be good. I use my cellphone - it only has 1GB, but its way enough for music, and it's pretty fast to add/remove songs when I get bored of them.
I simply think that unless someone would pay lots of money (like 300, which would be a TOTAL waste) on a portable video player, they're not going to get something they'd enjoy watching. Just imagine.. watching a whole 2 hour movie on a 2 inch wide screen.. it would be totally annoying.. Even if you had an expensive one with a bigger screen, you're not REALLY going to watch movies everywhere you go..
Examples of really expensive ones would be this :

But yeah, it's not really worth it to go for video.. maybe getting a portable dvd player would be a good option if you really want video. Other than that, the sony one you wanted would be good for music. Check out this link from the amazon website, it has all the media & mp3 players you could pick from:
