PS2 V7 No Soldier Modchip DVD+R

[Mana]

First of all excuse my following bad english. I'm a little out of practise.


I read a lot of webpages about Mod Chips, the versions of the Playstation 2 and DVD Backup.
Two months ago i bought a Ricoh MP 5125A DVD burner, wich only can burn DVD+R/RW medias.
So i know, PS2 equal to or above v5 can handle DVD+R so i got a V7 PS2
Because i am not a genius in soldering a modchip i decided to buy a No Solder Modchip. A few pages say there exists No Solder Modchip vor PS2 V7, another pages say there aren't. SO my Question is: Does a No Solder Modchip really exist or work on V7 and can i boot DVD+R backups using the AR2 change trick without having an original DVD Game?

I hope somebody can help me. I'm looking for the cheapiest way for getting this problem solved, because the really good mod chips inclusive the installation service is a little bit expensive here for me.
