I was hoping to self-pimp my thread on the Aiwa PCDP.

I am keeping the Aiwa and will be putting my Sony 401 on sale soon. The Aiwa is indeed quite a nice PCDP, aside from the relatively weak headphone output (only when compared to previous generations of PCDP). To maximize the Aiwa's headphone output, I ordered a pair of Sennheiser PX200; they're going through a burn-in process right now.
BTW, the Aiwa EX-EV501R is no longer on Walmart's website. However, my local Walmart still has several available.
For a brand-new PCDP with decent headphone output, defeatable anti-shock, CD-R/RW playback capability, and a $45.00 price tag, the Aiwa is highly recommended!
