Sean Bradley's kit on etsy is probably the most complete and reasonably priced kit (as far as quality is concerned).
Edit: the forum is not allowing my link to work correctly, so look up Sean Bradley on etsy, and you will be able to browse his products there.
Keep in mind that no helmet is included in this kit, and that you still have to dig up all of your strapping, padding, and paintwork. I'd give yourself at least 60+ hours to complete the suit once it arrives, but it his kits are awesome.
