I get a lot of gap v4's for some reason. (including my own but with a new laser of course) Lasers are only just hanging on in some of them but they go ok with a bit of tweaking... Always gotta let them know they'll be up for a A$70 laser soonish tho.
Here's a cheapmod Duo2se in a v4. Great chip! Bulletproof.
THis is also my official entry into the worlds shortest (complete mod) wire competition! Damn those eject lines...ur lettin the team down!
