I have been using Host4Geeks for over a year and I haven't had any problems. Their packages are well structured and there is no hidden costs.
Their support staff is professional and well mannered. Whenever I required any assistance, their online chat & email support channels helped me in a timely manner. The staff (billing, sales & support) understand their products and is able to answer any question regarding their services within minutes.
In all the time I have worked with them, I haven't experienced any downtime or other availability issues.
I can recommend Host4Geeks for standalone & reseller hosting.
