question about..mods..

[StartingLine]

i was thinking on modding my 5001 model
and possible upgrading my 39001
console that has a messiah with a matrix infinity or a dms3

for the dms 3 the price with the mod and instalation complete is..
140.. and for the matrix infinity 120..

are these 2 the best?
or do you recomend others?..

by the way is there any mod.. that let´s you play pal games on a ntsc console without patching?

thanks..
