If you're in the US, have a look at rollerwarehouse or aggressivemall websites. Truth is if you're just starting out, mostly anything will do. Bladings dead, there's not much to choose from. USD, razors, remz, valom K2 sort of, and rollerblade are fine.
You just have to realize they aren't ski boots. If you go in thinking they will be, you'll think all of them offer no support and are too wobbly. You'll also have to keep in mind that you're not skiing, you don't have a nose and tail to land on and you don't need to afterbang everything.
