got one

be aware that when you buy from them, they won't register your domain in that instant, you will need to wait for... (I don't know how many hours) until someone from their staff come and registers the domain for you manually !!!

personally I don't like this

I don't like that kind of wait too, but I will try

Do they allow push?

Yes it will take 24-48hrs to get your domain after verification of your Id
