I thought it may be interesting to share details of a few online services or shops that I recommend, and for others to do the same... would be sensible to keep it to businesses that have a national reach. (I know there is another thread in the members section but it's a bit tired now )
Accu.co.uk (Accu) http://Accu.co.uk
Precision screws, nuts and other hardware. They aren't cheap but have a very extensive range and have been very consistant in terms of quality of product and service.
Mouser.co.uk (Mouser Electronics) http://Mouser.co.uk
Electronic components. Recently wanted to replace my secret button as it was broken, and decided to replace the connector as well. I stumbled upon them, and was staggered by the sheer volume of parts from automotive to home automation... it is impressive.
Carbuildersolutions.com (Car Builder Solutions) http://Carbuildersolutions.com
Lots of fastenings, switches, gauges, edge trim, adhesives... you name it. Used them for a number of years and always consistant.
I'd be interested to see what you've all found
