Have a look at the Explore Scientific ED80 APO Triplet. I have one and the quality is great for the price, and they are on sale at Opt Corp right now for $680 USD for the white tube Essential model - so you can probably get one for less than the GST threashold. Of course if cost doesn't mean anything to you and you want to buy a Tak then do that, but the ES will do all the things you listed and give you greater aperture than those you listed.
