I remember both Tandys and Laskys. We had both in the centre of Birmingham. Tandys was similar to Maplins, whereas Laskys sold various hifi brands such as Quad (I remember seeing their Electrostatics there).
In my early twenties (just over 35 years ago now), I bought a JVC STEREO VHS video recorder from Laskys, stereo on VHS machines was a new development at that time.
I was in my first proper job, a trainee computer operator. From memory the machine cost me £650 (the same price that I had paid for my Sony 27inch (or was it 29 inch?) Trinitron TV) and I had to have the show model as they had no boxed models. I asked the salesman if I could have any discount and the miserable beggar said no, at least you know this one is working okay. I felt a tad peeved but was pleased with the recorder.
