Since James has not identified what "his use" is, the wide ranging responses to his question generated answers to the more general question of: "What RF signal generators are available? And at what cost?". The very wide range of generator costs identified by other posters to this thread offer few if any inexpensive solutions. Inexpensive probably means "build it from scratch" or find a kit. As others have mentioned, aside from generating the signal, knowing what frequency it is on and being able to adjust the power level are probably the minimal characteristics of a useful generator. A transistorized wide frequency VFO with band-switchable coils/caps is easily made. This coupled with a frequency counter and a step attenuator makes a useful generation system. A DDS-30, DDS-60 or equivalent is better that a VFO-type oscillator for some applications, but will depend on your needs. Google for Frequency counter kit and step attenuator kit. Scan the unmentionable auction site to see what's available. Having separate pieces of gear is a plus because each may be used in more than a single way. Gear such as a crystal oscillators, RF detectors, RF mixers and the like can be easily added to the mix to give you more testing/experimenting capabilities. Also consider that simple, usable electronic equipment based on the PC sound card are easily fabricated. Do some research, decide build or buy, go for it!
