Just make sure you get the real thing and not the clone...avoid buying through eBay. Buy direct from the manufacturer. Several of us have done this. Any will be able to advise. From an appearance standpoint, the clone and the real thing are almost indistinguishable and could be impossibly indistinguishable in an advert on eBay.
There are lots of different products out there ranging up to those products that are monitored by a third party and therefore have a monthly fee (up to £300 and ~£25/month). Several on here have those devices too and are very pleased with them I believe. You pays your money...etc etc.
I think there's a critical mass of nobbers on here who have bought the Xenun Tracker. Not heard of any problems to date (damn, that's the kiss of death)
