Hi.  Does anyone know of a reasonably priced bar code wand (<$100).
I've used a homebuilt one with the HP HEDS1000 optosensor but a real
wand would be nice.
Also for anyone who has built a scanner - what have you found to be the
most reliable way of reading code 39.  I have tried timing dark and light
areas and them using a lookup table but the scanning rate has to be very
constant - any ideas for a better method ?
Thanks
