Does anybody here use Tactical Arbitrage or Oaxray?

I'm going to change gears, use my IM assets to start pushing traffic to ebay/amazon stores and such.... and I want to go with good software + chrome extension for most of my product research/on site implementation. The funny thing is, almost all of them make claims to bet the best or most accurate, and you don't really know until you use them.

Just lookin to any vets that have already been doing it for a while if they have experience with either.
