From aerospace to medical equipment, precision resistors play a critical role in the success of a wide range of industries. These resistors may be small in size but their impact on an electronic device cannot be denied and the precision resistors manufacturers are working day and night to give us the best of the best. Designing, producing, and distributing a variety of resistors that satisfy the needs of their clients is the responsibility of precision resistor manufacturers. High levels of accuracy are employed in the manufacture of the resistors to guarantee that they perform within the precise tolerances necessary for the devices they will be used in. The reliability and toughness of the resistors must be guaranteed by the manufacturers to withstand the demands of the applications for which they are intended.

Wirewound, thin-film, and thick-film resistors are a few of the different varieties of precision resistors. Manufacturers must take into account these elements while designing and constructing their resistors because each type has distinct advantages and disadvantages. For instance, thick-film resistors are more affordable while wire-wound resistors are noted for their great precision.
Precision resistor manufacturers must deliver outstanding customer service in addition to high-quality resistors. This involves providing technical support, quick and effective delivery, and affordable price. To ensure that they are creating the most advanced resistors available, the producers must also stay abreast of the most recent technological developments in the electronics sector.

My metal thin film resistors from amazon were approximately 50ppm/dec C when measured (advertised as 100ppm). My ebay carbon film resistors from china were approximately 250ppm/c when measured. Not too shabby. I don't think the tempco was advertised.
A yaego precision resistor kit (e96 values in the 10k range, marked 100ppm) had a tempco of 7 ppm on a random resistor. Much better, but not always necessary
The one thing you really need to watch out for is ebay ten turn trimpots. The single turn panasonic trimpots are ok (250ppm) but the 20 turn bochen's are a joke.
In order to be a reasonable engineer you should probably have an assortment of cheap and high quality parts.
I don't think there is a good need to use a 20ppm/c resistor to current limit a indicator LED or as a pullup/pulldown for digital logic, the most heinous of values are used for this purpose (see dave jones video on carbon paste resistors!, I think he said they were like +-50% ). I keep a book of china ebay metal film resistors (as many values as you can get), a book of carbon film resistors and precison books that have 5 each of e96 values per decade (still working on this expensive collection).
If you find my previous thread on trimpot temperature co changes I detail a crude but effective test setup for measuring temp-co with common items, you would probably want to make it a bit more refined if its for a science fair though. You will need a decent ohm-meter for this experiment.
