Query: Great while it lasts . . . but it doesn't

I bought this player on 12/20/2004 and have used it heavily until last night, 5/28/2006, when it inexplicably just quit on me. Online research has revealed that this unit suffered widespread firmware issues. Mine is now out of warranty and I can pay $182 to have it exchanged for a refurbished unit "of comparable value" or $133 to ship it out for repair. No thanks, Sony.It's too bad - it really was a great player while it worked but I'm not going to sink $133 more into technology that is two years old. My last Sony player cost less than this one and was eventually replaced after 4 years just because it was so old school (non-progressive). What's up with that, Sony?
