No Idea dude...
If you really want a solderless solution wait until those Spider chips are sold and pick one up.. Be one of the first Beta testers for em and let everyone on the forum know how they work since any new box is going to be a 1.6 (if they ever come out with a 1.7..
But if you want a regular solution youre gonna have to work a bit harder.. Rebuilding the LPC ports requires more soldering than soldering a regular chip. But if worse comes to worst thats what you're going to have to do.. Solder the pin header and solder wires to it for the LPC rebuild. At that point probably any decent chip would do the job.
Like the XBIT, Xecutor 2.3b, Xecutor 3.. I personally have the Xenium ICE in my 1.6 box and I dig it. Hasn't let me down yet.
Also chipping an Xbox is much easier than a ps2 by far. So you might be able to get a buddy who is familiar with a soldering iron to do it for you.. Could even take a shot at it yourself.. There's a novice method for rebuilding the LPC ports on the 1.6.. Uses bigger points to solder too.
But whatever the case.. Good luck!
Spedmetal (not to mention countless other great installers on FF) does a bang up job on PS2s and if he can do that well with those tiny vias an xbox mod should be cake. You can get a DuoX2 done by him for 60 bucks + shipping there.. return shipping is included in the price of the chip.
