How Do You Prototype with QFP-Only Components?
I just have a PCB fabbed.  Its incredibly cheap to do so nowadays unless you need exotic materials or construction parameters.    

Making your own PCB is reasonable for hobby work but when contracting for $150-200+ an hour as most design houses do, having a 4 board 4 day turn done is just cheaper than screwing around with adapters or etching your own copper.
