If you are looking for a basic 10W pep rig for 20m (or 17m) you can do a lot worse than build a BitX kit from Hendricks QRP kits.The basic "no nonsense" design came from India but these kits are well documented and on a neat PCB. See http://www.qrpkits.com/bitx20a.html . The full kit is $180 in the USA.

Hendricks do a number of other (mainly CW) kits of interest.
