danacath, all the things I listed are supplies that you can get almost anywhere. The stickers you buy at Hobby Lobby are the same brands in other places etc.
Things like stickers, die-cuts are more about finding what matches the pages you are doing. They have stickers for almost every occasion just finding the right one for you is the only thing to worry about.
The place I would suggest going with quality over price would be in purchasing albums. Whatever you do if the album doesn't hold together it isn't good.
