The Connect 3D works. The guy who made the GTO2 mod confirms that:
"Not only the Sapphire GTO² can be modded, the regular GTO cards from Connect 3D are also moddable"
Success 27 : 1 Failed (last update Oct 25 2005).

Cost saving tip: this card is cheaper than the GTO2. The GTO2 will reach no more than 10% better clock speed than the Connect (let's say 540 x 500), but it costs 30 to 40% more.
EDIT: Success rate updated.
