Accoding to my mini research, this is the best system I have found so far.
-Full 12 month gaurantee
-FREE Technical support
-FREE Next Day delivery
-Massive 60 day battery life
-Movement alarm can be set to alert you if your vehicle moves more than 200m
-Built in antennas
-Any person with average knowledge can install it.
-Cost: £200 approx
-You may need to charge it every 30-60 days. I have sent them e-mail to find out if it can be fitted on permanent basis.
-You may have to put some balance in pre-paid sim to keep it active every 6 months (I guess).

and their demo unit will send you instant message with the location of this demo unit.
I have also looked at RAC trackers but they come with annual subscription fees which is not cheap either.
If somebody wants something cheaper than this, then there are few options and those item are manufactured in far east.
