Hammertap.com - any info about them?

Has anyone here used Hammertap.com for research. I've been using them, but the research is based on eBay USA, and I list in .co.uk, so it seems a bit pointless for a European user?
As the prices/services differs so much from the US to UK.

Any info would be appreciated.

Seriously, no one ever used Hammertap?
Would like some feedback on them?

What about Terapeak - they look very promising?

Hi Obelix,

I've used Hammertap, however, for US research only.

I have used hammertap and it does do well depending on the product. It gives you the best day to close and average selling price of items fairly quickly. Everything is based off raw numbers. The only problem I forsee is with high fraud products(electronics). Take for example the XBOX 360. If you used hammertap it will probably give you a higher average price than the actual price on ebay because of fraudulent buyers. If you search completed items on ebay you may notice a closing price of 1,000 dollars. Wow! 3 times retail price! This of course is not a legitimate sale and may scew hammertaps numbers.(This is an assumption, not a fact) I personally cancelled hammertap before the end of the free trial because I feel that my own research and experience is much more valuable than any compiled batch of numbers. Plus, it takes just as much time for me to research using hammertap as it does for me to conduct my own research. Whether you use it or not is up to you, but doing things for yourself can be the best way to learn. Hope this helps you in your decision. (This was US usage)
