Kentex is the most reliable among those US shippers, but highly expensive, especially for large items. They will charge volumetric weight, which seriously adds to the cost of the item and sometimes you end up paying almost same price as local vendors. I would advise you consider others, such as iMail Kenya, who only charge dead weight. I have shipped small items with them and they deliver. Just check those that don't charge based on volumetric weight, otherwise you might regret cuz of costs.
