Magic V vs. Smartchip

[Nosforatu]

I've got a no-solder chip and swap magic and am sick or stuff not working and the hassel, but mainly certain games not working (eg Champions of Norrath, oh so good, I'm not risking it getting damaged) and so I decided it's time for a real modchip. I've been checking out the available modchips and have decided that DMS3 is a lot of money for things I don't need and that Messiah 2 and Magic V are basically the same thing, except that Magic V is less expensive (and I haven't really even found many places carrying Messiah 2). I have come down to a toss up between 2 chips: the Magic V and the the Smartchip. Would anybody be able to make suggestions? I have a V7 ps2 and so if there's any known problems with either chip's compatibility, please let me know. I've found Smartchip to be less expensive, but I'm wondering why? What makes each chip better or worse? What are the limitations of each? (dvd9 backups, ability to turn off when playing originals online, that sorta stuff) Also, where can I get either one of these installed for a good price, and sent back to Canada? And do you know if any of these places would want to keep my no-solder and Swap Magic discs as a sort of trade-in? Thanks guys.
