Digital is all the rage these days and for good reason. The real world is analog however - temperature, air pressure, sound, electricity - these are always perceived and measured in the analog realm. Unfortunately, most electrical engineering programs focus exclusively on the digital realm.
Texas Instruments' primary business is making chips to do various functions - a lot of these chips are analog. They came out with a training circuit board for university classrooms and at only $99, it fits right into the hobbyist's workbench as well.

Everything that an analog engineer needs
ASLK PRO comes with three general-purpose operational amplifiers (TL082) and three wide-bandwidth precision analog multipliers (MPY634) from Texas Instruments. We have also included two 12-bit parallel-input multiplying digital-to-analog converters DAC7821, a wide-input non-synchronous buck-type DC/DC controller TPS40200, and a low dropout regulator TPS7250 from Texas Instruments. A portion of ASLK PRO is left for general-purpose prototyping which can be used for carrying out mini-projects.
There is also a comprehensive parts kit for $70 - the price is actually very good as the kit is extensive.
