Duox2
 

Is DUOX2 a good modchip for Xbox or would you recommend another over it?

I don't know about the DuoX2, but I have an Xecuter3 CE and it works great!

Did you install it yourself? Where did you get it? I seen those chips advertised and was thinking that might be a good way to go. I have a Seagate 300GB harddrive that I want to put in the Xbox also.

I have the DuoX2 and I think it is one of the best chips avaible considering the price and what its capable of. Simply loving it. I see no need to pay $70 for X3 when you can get a DuoX2 for $20-30 instead and it gives the same capabilities even though it doesn't have as many accessories.

Kinda easy to install too IMO. Of course some soldering skills is good to have regardless of what chip you're going to install.

Yes, i did install it myself, i have a lot of soldering experience.
Most on-line mod chip stores should carry it, i got it from here: http://www.xbox-modchips.com/
