Vislink (LON:VLK) has been recommended to me by a few different people now and mentioned by a couple of bloggers (I know Pauly Pilot is keen and I've a hunch there's someone I've forgotten..), so I thought I better check it out. The offer of a value opportunity shouldn't be refused! I usually start with a sentence of two detailing what the company I'm looking at does, but recently I've been having  a bit more trouble with this. It's easy, as a layman, to understand how a company makes money renting vans or building houses.
