Im getting the Dynatron Cooljag 1U for my 9700pro. Its a low profile copper hsf designed for athlon cpus upto 2200 palomino. Due to its low profile (and the fact other people have used this on their 9700's) it would be perfect...
None of those coolers cope for the shim on the 9700pro, meaning it may be worth removing it for 100% contact.
If I had to chose between the TT and the Vantec, I would go for the Vantec based on the reviews ive seen...
