Kyle Baker's Plastic Man is very good, but it's not really the Plastic Man from the DCU it's very much the Jack Cole Golden Age version of him. It's set in the DCU but it's played for laughs but it's very well crafted, beautiful to look at, funny and surprisingly poignant in places. It's a very cartoony book almost to the point of letting the pictures do everything and trying to use as sparse dialogue as possible. Kids would love it but it's not written down for kids in anyway. It won't be what everyone wants out of a comic (especially if you just don't click with the Jack Cole style humour) it certainly wasn't what the public wanted when it was released it bombed rather badly though it won loads of awards and huge critical acclaim but you might be pleasantly surprised.
If you really want to know what Plastic Man is like in the DCU just read JLA from Morrison through to Kelly. They do more with Plastic Man as a Superhero than any other book has ever tried - and then Plastic Man utterly failed when they gave him all the deadbeat dad and grimdark stuff after he left.
Have no idea why a search didn't turn that up.
