A Mac OS X Clone? I also build Mac clones I'm not sure if thats what your talking about though
Anyways I would go with Gimp IF you can't get you hands on photoshop
Just because photoshop is an awesome program. Actually if you have a Mac I can mail you a copy of Photoshop even, just let me know. If you want to just change hue and saturation you can use preview (if your on mac) or pixelmator is a light weight cheap alt. to photoshop as well.
Another thing I started doing as a result of sketching(by hand) the basic's over and over again of the bike when I'm just trying to draw a different tank only for example. I simply take a good side shot... non complex image of my bike I want to use and take a eraser/white pencil(computer tools not hand) to the tank and blank the tank/seat/ whatever out I plan on modding and printing them out. This allows you to draw and even color in what ever you want and get a real easy mock up. Need another copy instead of spending an hour on the comp making a new image or drawing your whole bike out by hand for a tank or seat option. This method proves to be really handy. I'll upload a pic when I'm on my main computer of the one I did asap for ya.
Hope this helps, thanks for filling us in with the comp info.
