I was looking for a cash purchase scheme but was wary about the bad press these companies, I found Kent Property to be very straight forward I found the info quickly and without having to delver down through a million and one pages.

Nice, easy to use site. Shows free gifts at the bottom of the page for each phone model.You can even test their system by clicking on the actual tariff you want and seeing all of the retailers deals they have compared.

Phones Limited is a really easy to use website with manufacturer links in the menu down the side. The site even matches similar handset models at the bottom of each page if you are still unsure of which phone you are interested in.
Email response was quick and positive to questions and all links tested worked 100%.
