Check out this neat QRP 40 meter SSB kit from crkits.com: This neat little transceiver is available as a kit for $115 or $155 assembled (plus shipping). An optional mic is $20 and internal speaker is $4. It draws only about 2 amps in TX, making it a neat choice for hiking or field operation on batteries. The tuning range is about 20khz, available in 5 different frequency choices. I've attached the complete brochure. Pretty neat!
