I found the Xenium Ice very easy to work with. The chip has FTP and a Hard Drive replacement app already on there. It walks you through each step of replacing your drive and clones your current one to the new harddrive (you just put it on the DVD rom cable while doing the HD upgrade wizard).
I did the no solder for my buddy. I placed a few sheets of folded paper between the DVD drive and the chip just to make sure it wouldn't move around. It hasn't given him any problem for the past 6 months.
Process:
Install chip (15 minutes)
Boot XBOX
FTP in and copy over a bios file
Select to flash new bios file and point to one on the hd
Start HD wizard to replace drive and follow instructions
Install Slayers
Done in an hour or two depending on how much you are copying from drive to drive.
