I'm wondering if you guys/gals can point me in the right direction. I'm looking for a shared web hosting provider that offers very good PHP/MySQL performance as well as excellent uptime and that doesn't oversell even to only a small extent.
I'm looking to spend no more than $15USD/pm (preferably around $10USD/pm).
Here is what I'm looking for in detail:
500MB disk space (with ability to upgrade later if needed).
5GB bandwidth (with ability to upgrade later if needed).
Proper (i.e. not "addon domains") multi-domain support for at least 2 domains.
With those requirements almost every host out there fit for you, the only thing is that not every host would give proper multi-domain hosting, since that would require WHM access (on hosts with cPanel). I do remember some hosts here on WHT that offered such things, but can't remember quiet well which one was.
There are plenty of host that is within your budget. Though not many that may offer WHM (true multi domain hosting) as TheLaw mentioned. But two host you can try is axishost.com and dotable.com. Both offers WHM and is within your budget.
Good luck with your search. And update us with your choice
