LED bargraphs

hello everybody
i learnt from the forum that it is probably easiest to implement a LED
bargraph by means of an LM39xx... However, are there some manufacturers
that offer a broad range of LED-line designs? for example the number of
LEDs, the size and shape of LEDs, the colours and so on?
thanks a lot for your advise..
have a good day.

For hobbyist use the choice may be a bit more limited (though you can build
your own bar in discrete leds of many shapes, sizes & colours).

Some 2-20 led bar modules
http://www.rapidelectronics.co.uk/rkmain.asp?PAGEID=80008 and they'll all
stack for longer bars.

Note there are other bargraph ICs as shown on the page, a lot cheaper than a
3914/5/6 if you only want a 5-high..
