There is always potential for overload issues with shared hosting but after endless problems of slow loading with one host, so I searched for a better host.
I found Gigapros via Google search and since I've signed up, every single question I have had has been answered immediately and intelligently. I've noticed no downtime and my site loads faster than ever. I am the type of user who knows just enough to screw things up. They have always politely and quickly (less than 1 hour usually) resolved my problems (that is, fixed my mistakes).
For someone looking to host a few things this is definitely the best inexpensive route to go.
They are very keen on maintaining their level of service, can highly recommend these guys.
