There are ways to breadboard with SMT parts without a PC board.  Use  
common stripboard or donut board (individual pads).  When you need to  
place a chip, put down a small strip of Kapton tape first, just a bit  
wider than the pin spacing.  Kapton is a high temperature tape,  
transparent, golden brown in color.  Glue the chip to the Kapton with  
a dot of superglue.  Use #30 Kynar wire to route the pins to the  
appropriate pads / traces for your circuit.  0805 components will  
space perfectly between donut pads or stripboard traces.  You may need  
a magnifier lamp to solder individual wires to SOIC pins, but it's  
very doable.  Just practice before soldering a 0.4mm chip.  :-)
