Specific Mondchips for Ps2

In the spirit of christmas, i was planning on buying a modchip for my ps2 to burn some games (and save some money). This is the modchip i have come to select- http://www.modchip.com/ps2/slidecard.htm

does anyone no of any faults wiht this befor i buy it or recommendations on a better one. The reason i picked this is cause its relatively cheap and i dont have to open the system.

Last do u no if it can play copied ps1 games?

thanx
