Hi stirfry,
I'm not too familiar with some of the tools you mentioned.
But I can say that Terapeak as well as Hammertap are 2 of the most commonly used (not to mention recommended) research tools for eBay.
SaleHoo actually offers two tools you can use for eBay, one is the Auction Inspector and the other one comes free with your membership - our Research and Analysis lab.
- The Research and Analysis Lab is a powerful tool for finding niche market opportunities on eBay and on the internet and general. It has recently been given a complete overhaul, and now come packed to the gills with tools for finding new niches, comparing products, analyzing trends, and uncovering sales data from eBay.
Among other things, we have fancy graphs to show you whether demand and sales for your products are increasing or decreasing, so you don't buy a whole lot of stock that won't sell. We can also tell you the best time and day to end your listing, the best category to list it in, and the average start and sale prices for your products.

- While the Auction Inspector inspects posts on the eBay "want it now" section and tells you which products are wanted most often. Not only that, but it also analyzes responses from sellers, so you can immediately see the areas where sellers are already swarming, versus the areas where there are clear, open pickings for you.
Here's how it works:
* Choose the eBay site you want to find a niche on (USA, UK, Canada or Australia)
* Select which categories you wish to inspect for trends (eg. collectibles, consumer electronics) or use a keyword.
* Sit back and let the software do the rest!
