USED V7 vs. NEW V12

[dark_flip]

Well,
I currently have a Version 1 PS2 which isn't the best to do a mod on. The lasers suck. I kind of wanted a vote here among everyone on what is the best way to go. I'm looking at a USED V7...you may ask how well has been taken care of...or how long has the person had it?...my guess is as good as yours. Or should I get the new V12 PS2 and just deal with it? What do you guys think? I've read some of the stuff posted by spedmetal about modding the V12...and there hasn't been alot of problems reported...I don't like the fact that I can't use a HD...but I'm not to found of getting a used and abused V7 either?

Also...what is the actual way to tell if it's a Version 7...I read that the model number must read SCPH-39001...however in one of your guys avatars it says
V7 (SCPH-39003)....so is it any SCPH-3900_?
