Getting component samples from companies. Which ones worked for you?

[Mint.]

So I was thinking about asking for some samples from some companies later on when I would need something. Which manufactures worked for you and what was their service like?

Primary rule of using samples is avoid abusing it. At least order what you need, not what you would need or better what you need and can't get by other means (insane price, no distributors etc.). The more we abuse this, the less we'll get in the future.

Digikey, Mouser, Farnell.
Instant availability check, reasonable cost, quick delivery and No questions asked

Maxim, Microchip & Analog Devices

It was easier in the past, but now the reps want to hand deliver the samples and always want to know what they will be used in.
