Help..Which of these 2 MODs is best for me?

[simonwood]

I have no idea what I'm doing. I know a few people who are fairly good at soldering and was wondering which chip I should get. I don't want to send it to some one and let them install it for me.

I either want DMS3 or Messiah2. Which is most reliable and stands the least chance of messing up my PS2.

I have a US v7 PS2.

Thanks, I just found this forum today and dont know much about mod chips.
