I'm looking to resell hosting packages. Has anyone tryed Certa Host?

I've never heard of them. At first glance they look to be pretty good, they seem to have been around a little less then a year. I couldn't find any reviews on them.

I think Prozilla.com refers to hypershack.com that pops up certahost.com.
IMO, Prozilla.com account is available for turnkey sites and they suggest Certahost.com. I also didnot find any review about them. You should go through this link, it might be helpful to you.
You should choose reliable and reputed reseller web host with professional and quality 24/7 tech support along with nice features.

Can you post more information on features you want to use?

Regards

Never heard of them.

Certahost.com was opened in january 2005, I haven't heard any bad or good reviews about them yet. Might be a good sign, use at your own risk :P

Me too never heard of them.
