Ok so with all the light gun games available now (like Umbrella Chronicles, Links Crossbow Training, Ghost Squad..etc), I decided to research some of the ones available now including :

- Wii Zapper
- Wii Blaster
- Wii 2 in 1 Combine Gun
- Wii Cyber Gun
- Brando Wii Lightgun
- Nyko Pefect Shot
- Wii Gun Hazard

Personally, I think the Nyko's gun attachment would be the best considering the price and it's hand gun configuration. But some folks may enjoy the two hand configuation of the Wii Zapper or even the shotgun style Wii Blaster. And then again, some games may "feel" better with certain types of attachments.

Anyways if anyone is interested, I wrote an article reviewing some of the features and pricing of each light gun attachments here : Wii Light Gun Attachments

Keep in mind that none of the light gun games actually requires it. After all, it's just a piece of plastic that your wii-mote sits in!

I think a big deciding factor in the attachment debate is the value of the actual package. While most reviews I have read prefer 3rd party models to the Nintendo Zapper, Link's Crossbow training makes the Zapper very appealing for its price.
