Those are the major ones, there used to be some el-cheapo Chinese models like Sampo or Daewoo - but I haven't seen those around for about a year. There are also other 34" HDTV models from Sony - the cheaper 34XBR800 and 34HS510, and a cheaper Toshiba model 34HF83.
I'd put them in this order (highest quality first): Sony, Toshiba, Panasonic, Philips - though you might swap the last two.
From a cost standpoint, the Toshiba is the best value since their pricing is as cheap or cheaper then the lower quality Panasonic or Philips while not quite as a high quality as the Sonys its very close and Toshiba has a few features the Sonys lack. But the brand new super-fine-pitch 34XBR910 is the highest resolution HDTV CRT display available right now.
