G&G have a pretty wide range of AKs and I think all of them have a blowback version, I paid £145 for mine and it's one of only two guns I've ever left alone internally. It was just too good to need to try to make it better, and for the price you really can't go wrong.
The blowback G&G use also uses redirected air from the gearbox to push the bolt back, so there's nothing clamped to the gearbox as per other designs, meaning there's no added wear on the internal parts, so it doesn't decrease the life of the gun.
It is just visual blowback though, you're not going to feel any feedback from it unless you go for a TM, or a gas AK.
I agree with two_zero on the whole, I do find that TM get a lot of praise that's no less valid when talking about a lot of other companies, they just get special attention because they were the best a long time ago, because they were the first to do pretty much everything. Their reputation is quite definitively a remnant of their glory days, but that's not to say they aren't good, they're just not better than everything else on offer.
The recoil shocks are a very clever innovation and they get a great rep. AEGs with actual recoil. Get one if you can afford it, but if you're mechanically minded, you're never going to get recoil from an AEG as good as from a gas rifle.
