messiah chip available anywhere?

[martiemcd]

lik sang no stock.i am also unsure of whats going on with sony and messiah?should i get one now?also what benifits does it offer over the other chips avail{neo,etc}and price comparison.
is it the best way to go?also how much would be reasonable to pay someone to fit it?i know a guy who throws in a neo with dvd region x for forty quid,but would rather choose and get my own chip!
i have also seen a holder type thing that you connect instead of the chip,the chip then plugs into this,hence easy removal / upgrading of the mod chip.are they any good?
lastly,the boot c/d for ps1,{x.change 2 or something like that}does it work? thanks all!{thanx charlie@co}
