I am now looking for a high bandwith hoster and found this one:

http://www.kikko.com/package_eplus.htm

Anyone have any experience with them? Are they to be trusted?

Enter their name in the search box and you will find a considerable number of comments on Kikko.

As to other hosts you might want to consider, a few suggestions.

1-Just read as much in this forum as you can.

2-Post a request in the hosting requests section. Wait for responses. Search the forum for information and opinions on the responders. Provide considerably more information on your current sites and your plans so they can respond correctly to your needs.
