On this there are a few things which I would suggest you watch out for:- 1) Has the company been around for a while- at least a year perhaps? 2) Is there an individual or more than one individual clearly identified? 3) Does the company offer any explanation for supporting the Jaguar? 4) Does the web-site have a track-record, has it been around a while? 5) Does the web-site have a proper URL- or is it hosted in free space?
