The X-202-B is seeing a bump in cost. I purchased mine a couple of years ago for $850 or so, half restored. Another buck and quarter to finish it up, including a DIY cabinet. I've been keeping an eye on them at auction and in purportedly restored or "working perfectly" condition, I've seen the price anywhere from $1100 to $1600. Subtracting the eBay factor, figure around $900 to $1000 for one. A jacked up one will be $600 to $800 although I haven't seen one on the low end in quite a while.
On the tuner, well, I paid $250 for a FM-200-B, (the model just under the TOTL unit.) Damage was $250, original everything, pristine, box included. That should bring you under $200 for the 100b.
