http://myurl4u.com is sub domain based short url service, eg converts your cj link to http://www.awltovhc.com/xxxxx-xxxxx http://domain.myurl4u.com give it a try!
Agreed, I wouldn't use any third party service for affiliate link redirection. You can easily do this yourself, without the risk of the third party either shutting down or replacing your affiliate link with their affiliate ID.
I have to say, I personally would never dream of using a third party to cloak my affiliate links, no offence but there are just too many sharks out there. I use a nifty little script to cloak my links, it's not free but it's pretty damn good
Yeah, not just that ..using redirects like that you never know how the stats show up on eBay's side and it might get you flagged and banned.
