That's pretty impressive! All hand soldered? I wouldn't have the patience to do this many, maybe not even a steady enough hand.
The easiest would be to find these chips in DIP packaging, but of course many are not available like that.
One easier way that I can think of is make your own PCB and solder the components on. Reflow it in a skillet or hot plate ([Sparkfun's favourite low-cost DIY method](https://www.sparkfun.com/tutorials/59#Hot Plate Reflowing)).
There may also be breakout boards for these chips (I have some for SSOP packages on the way - that's a 0.65 mm pitch but only up to SSOP-20). The problem is that the breakout boards will become pretty huge, with that many pins, even if you put them in double rows which makes it rather breadboard-unfriendly again.
There are all sorts of adapters available for smd chips.
Leo..
They're indeed huge 
The QFP176 adapter is 61x61 mm.
But a great help for prototyping.
