Both are very unexpensive to build. You can typically build them for 4 Euros
(or less) and they work fine. A commercial product is easily 10 times this
price.
Several proven schematics are available at http://pikdev.free.fr but many
other are available on the Web.
I prefer parallel programmers because they are not dependant on
electrical characteristics of serial ports (some of them doesn't deliver
enough voltage).
Finally, PiKdev is a KDE-based (graphic) tool so you will not be able to use
it. Hopefully, PiKdev source code also includes a text only programming
software (named pkp) which can be compiled without any graphic environment.
pkp can be used in interactive or command line mode and uses
the PiKdev programming engine.
(see pikdev home page for details).
