[sdiy] brand names

[j vallier]

Hi

For commodity parts, you should have no problem with quality since most of 
the manfacturers have to struggle in the low-margin commodity market. Here 
are some insights:

Digikey/Mouser: ridiculous markup, but creating an account with a 
Distributor like Arrow or Insight is not practical for a DIY'er.

Sometimes these places sell parts rated for industrial ot Military spec, 
hence a higher price--check the part number on the vendor's websites to 
confirm ratings.

Radio Shack: i NEVER buy semiconductors there-- I ran into buyers for R.S. 
in Singapore several years ago and they admitted they by QC reject parts 
that don't meet spec and pass the joy along to you, the consumer. Explains a 
lot...
