Obviously, I meant /usr/local/bin/uisp --help :)

Weeell... you shouldn't listen to me, since me setup obviously is  
flawed:)

Like Theodore suggests, an STK500 will do everything you'd want. If  
you're a little economically minded and can make do without the more  
advanced features, choose the AVRISP. You would probably just want to  
program ISP anyway, and the only use of the advanced features that  
springs to mind is the enabling of the internal RC oscillator.

Instead of buying an AVRISP, you can build one according to these  
instructions:

With the suggested swapping of the 1200 to a 2313 with improved  
software of this site (look at the bottom):

If you're not experienced, you might wonder a thing or two about that  
scheme. Feel free to ask me... or save yourself the hassle and buy  
something:)
