Generators?

Looking around for tools found a website for generators and found them fairly expensive.

However came across www.ukhs.tv selling tools under the name of \Volf, the once well known and quality electric tool manufacturer \Volf Electrics Ltd of Park Royal Greater London who ceased trading in 1960's and the name was well known and stood out because of the in-complete W of their name and the quality tools they made, also pioneering the first DIY electric drill the '\Volf cub'.
It seems as though its risen from the ashes like the phoenix but I am a bit concerned the quality isn't there anymore judging by the prices.

Questionn: Is there anyone out there who has purchased one of the \Volf tools and has been happy with it? As you see I've tried to show the W by using back slash \ followed by capitol V
