You're going to get mixed opinions on here of course, but I would go with the HD-A35. I bought 2 of the HD-XA2's...One from Robert at VE and another on Amazon...Had nothing but glitches of one kind or another...Sold them and took a chance on the A35...(couldn't be happier)...
The upscaling is pretty darn good too...I personally couldn't tell any difference from the XA2...(from memory of course)...But I use an upscaling megachanger in conjuction with my MX-3000 (and DMX-3000 software) for all my Standard def stuff anyways...
