+1 for the XA2. I have both the A35 and XA2 (and have used the A1 and A2, as well). I was so impressed with the XA2 that I have 2 additional players in my closet that I picked up cheap when HD-DVD folded. The A35 is no slouch, but I threw a SD DVD in for the kids today on my XA2 (which I hadn't used in quite awhile) with my Pioneer 151 display, and I was quickly reminded how special that player is. The reason it hadn't been used in awhile is simply because I've been using my WD TV Live or PS3 to stream the kids' stuff from my server (they don't care about video quality, although it's still not bad on the Kuro), but I need to start using the XA2 again.
As qz3fwd stated, it takes a LOOOONNNGGG time to boot, but it's one machine that's worth the wait.
