I think my two statements absolutely go together. I think (read: know) the extra money she would spend on the Mits TV could be better spent on the DVD player. I would consider a DLP of that size to count as a "top of the line" TV for most viewers. Top of the line is all relative. To me, top of the line is an $80,000 Runco front projector. To most, it is a TV like she is looking at. I personally love DLP TV's and think she is definitely on the right track.
Back on Bose: if budget really is a concern, this is an absolute no-no. Money can be spent on MUCH better systems. Look at the KEF
KHT 1005 system. It sells for $799, sounds better than the Bose ever could, is silver and matches DLP TV's. The Mirage
Nanosat system. Also $799, silver, small, sounds incredible.
On the Cambridge unit: I thought I hosted a pic for it, but it must be showing up for me only. The unit in question is the 640H, and can be seen here:
