I think FTDI would have sold more of these devices if they had made 
available a DIP package. Either the 232 or the 245 are, and will 
remain, very good quick solutions. But, if absolute reliability is not 
too much of an issue, you can do a USB device with just the 2313 - see 
AVR309. The firmware needs a very small mod to assemble under studio 
4.12 and there's a working version for the Mega-8 in the zip file too. 
I tried it the other day and the demo source code assembled and works 
a treat, even comes with a Win32 Application. But remember there's 
little error checking and it relies on a noise free environment, so 
it's a hobby-solution rather than a real-world solution ...
