I would take a look on Pioneer SP-PK52FS 5.0 and Dayton Sub-1200 or Dayton Sub-1500 for your budget.
Out of your options I have never heard of Taga and I haven't heard those Jamo speakers either, so I can't say much about them. If I had to choose between them I would pick the Jamo just because I know the company.
Edit:
If you have those said speakers available locally, go and listen to them if those are your only options. What ever sounds best to you is better pick.
