If you're certain the rig is fully functional and the physical condition is as good as you claim, I think $1000 is a steal, even if the rig is stock (i.e. has no optional filters or other accessories).
I say certain, because sometimes, with older units, there can be intermittent problems that you might not spot until the rig has heated up a bit. Mine has a 40 million serial number, and was advertised as being 100% functional. Well, it was more like 95%. There was a problem with distortion in RX and TX audio on SSB (accompanied by noise in the monitor on AM), but it would only show up after the rig got really warm, so it wasn't noticeable with just casual 'tire-kicking' tests. Luckily I was able to fix it myself (cold solder joint on TC1 of VCO2 on the AF unit), so I didn't end up having to put any more money into it.
Goodies that add to the value are:
- Having additional analog RX filters. You should be able to tell by cycling through the 455Khz and 8.83Mhz filter selections, though to be positive I'd take the bottom cover off and have a peek.
- Having the DRU-2 digital recording option and/or the VS-2 voice synthesizer accessories installed.
- Having the RM-1 remote keypad. I'm pretty sure the rig is supposed to come with this, but sometimes they get lost. (You really only need it if you have the DRU-2 option, so sometimes they get put in a drawer and forgotten.)
- Having the original hand mic. (These tend to get lost too.)
- Having the complete original manual set (user's manual, communications manual, schematic diagram manual). You can get PDF files of these, but I like having the dead tree media versions around.
- Having the original boxes and foam packing inserts (trust me: if you ever need to move the unit, you'll want these).
The lowest price I've seen one go for was $1500, and that was for a 40 million serial number unit, stock, without the original boxes.
The highest price I've seen was something like $2300 for a 90 million serial number rig, in good condition, fully loaded with filters, and with the original boxes.
(I paid $1600 for mine, and I consider that a good deal: although it was a 40 million serial number and not in mint shape, it came with _all_ optional filters installed, had the RM-1 unit and all the manuals, and the original box and foams. The seller claimed it had no filters installed, so having it show up fully loaded was a nice surprise.)
Anyway, at $1000 for just the rig, I'm already jealous.
If you have any of the stuff listed above too, then that's icing on the cake.
