how hard is it to install messiah?

[ddr_bboy]

i was wondering how hard it would be to install the messiah. i dont really think there is anyone around where i live to install it so i am thinking of getting one and installing it myself. is it really that hard? are the instructions clear? im 14 and have no experience with this type of stuff but i think i might be able to do it. please reply, i need to know because i dont want to screw up my ps2. also are there any external or no solder modchips for a V1 ps2 that can play dvd backups?
