You-Do-It is a hobbyists playground. Anything you could imagine you'd ever need, they'll have it. I went in last week asking for the most obscure electroniccomponents and there they were!
Think Spags for geeks and you get the idea. I've been going since I've had a license to drive there and always walk away with more than I expected. Amazingly knowledge staff as well.
We are a long established professional electronics speciality firm with two huge showrooms of audio, video and electronic products/accessories like nowhere else!
