We really have wandered off topic here, sorry....
I know quite a few people who still have these TVs, often in a game room. Setting convergence on one of these Tvs (like my Toshiba) is certainly a challenge - first, switch the TV on and leave for 30 minutes to warm up. Then go into the service menu through a "secret" button sequence, select the convergence grid, a multipoint convergence grid will appear (actually three grids, one for each color red/green/blue.) Put over the TV screen a preprinted sheet of plastic with the correct grid geometry. Use the remote to select just one color (usually green). Adjust EVERY convergence point so it is lined up with the grid. A major task, since adjusting one point moves the ones close to it. When the green is finished, adjust the red and then the blue.
Elapsed time - maybe three hours. There are separate adjustments for each input on the TV, by the way, so if you wanted to set them all it would take a weekend.
You might also have to adjust the mechanical focus of the three guns.

Plus if you want to set up everything, you have to use other service menu settings to correct for distortion, color intensity and so one.
My guess is that to completely calibrate one of these TVs would take around 20-30 hours......!!

Which is why an ISF calibration cost almost as much as the TV, but the results were well worth it.

I replaced my 55" Toshiba rear projection CRT TV last year, and I just replaced my last direct view CRT (a Mitsubishi 27") last month. The SD programming from DirecTV looked much better on those sets than it does on any of my LCD or plasma TVs.

Yes, SD on any CRT based system is typically much better than any flatscreen TV. Plasma is usually better than LCD, but some LCD TVs just have a terrible SD picture.

More than I guess you might think.

I can't imagine that there were that many HD CRT projection TVs to begin with.

back in '03 that was about all there was for a "reasonable" price.
