Advice needed on Slot 1 Cooler

[Gameboy999]

I am looking for a low-priced slot 1 cooler and have narrowed my search to these three (but if you know of any better ones, please let me know):

Vantec PD5030
Global Win VGS08H
Golden Orb Slot 1

Has anyone had any good/bad experiences overclocking using one of these? All input appreciated.

Thanks
