Actually no future pr checker tool is reliable. And iwebtool has basically that tool that has some importance. Cause you can check your current pr using google toolbar itself which is more reliable. So it would be good if which feature of iwebtool is termed as unreliable.
iwebtool.com just showed my site finally had a PR of 1 this afternoon, now it shows back to zero, damn LOL
I have purchased links from iwebtool in the past. It's only five bucks, certainly a fair price for a directory listing, so why not? Yes, I know the internal pages may only have a PR of 2 or 3, but for five bucks I'll buy it. Do you think those pages will be PR2 forever?
