Kushitani makes some really nice expensive suits. So does RS Taichi. For about the same amount of cash, you should go custom with Helimot or Zooni. They are all local to you. San Jose...
Dainese also makes good suits off the rack. They come in different budget ranges with suits ranging from $700-$2000. And usually comes with backprotectors etc.
I don't know much about BKS, Spyke, etc. but I would think they are all comparable. However, I recommend you trying on the suit to see what's most comfortable and in your price range. You should also wear your inner suit, backprotector, boots, and gloves to be sure that fitment is seamless and no obstructions. A good fitting suit should hug your nutz and make it hard for you to breathe, walk, and raise your hand. It will stretch in time tho...
