kdawg , there are some feedbacks that mentioned the players which originally were 8GB, are actually hacked 1GB chips.
Choosing a player depends very much on your budget. Almost all players are able to play videos, music, fm, etc.
For a budget of less than $60, you could get an Actions chipset player, which plays .AMV encoded videos. The video quality isin't that great, but acceptable. Most hacked players are Actions chipset.
For $60 to $100, you could get a decent Rockchip player which offers better quality and reliability than the Actions chipset. Rockchip also plays .AVI encoded videos, which has higher quality than the .AMV format.
For above $100, you could get the higher ended players like Meizu, Teclast, Onda, etc. These are chinese branded players with regular firmware updates and offers better reliability.
If you wish to get a good deal, you can try ebay, but avoid the Actions chipset players and go for the Rockchip or the Chinese branded players.
A 2GB chip itself costs about $25-26 each, if the price is too low, something is not right. Always remember that if the deal is too good to be true, maybe it just is.
There are some sites which offers the Chinese branded players at competitive prices:
www.houseofdap.com - Managed by Tomas, one of the first few sites to offer Meizus and Teclast. They are based in China though.
www.mp4nation.net - Owned by razzer001 a member of this forum, offers very competitive prices. He is based in the USA, but dropships from HongKong (if i'm not wrong).
