I've head blurbs here and there about a 386 upgrade for PS/2 Model 25. I just want to know if these even exist?

I know they existed, because I had one!
I remember the insanity of installing a late beta of OS/2 2.0 on that system. It had the 386SX-20 upgrade, 4 MB RAM, and a 40 MB hard drive. I managed to shoehorn OS/2 in there somehow. I didn't have any HD space left over for anything useful, including the Windows 3.0 compatibility layer. But I did get to 'play around' with OS/2 before most people. And it was remarkably usable on that machine.
I'm thinking that sounds like a stock 25SX.
Ah, now that you mention it, and I did a bit of quick searching, it was a Model 30-286, not a 25. I was confusing the two models. And I know it was a native 286, not 386SX because I bought and installed the upgrade myself with my hard-earned high-school-job money, just so I could install OS/2!
(I had forgotten that the 25 was the model with the built-in monitor. I thought that the 30-series was part of the MCA branch, and that the 25-series were the ISA models in that chassis, not a separate chassis.)
Now is there any chance of getting one of these?
For the the several 25SX units I have, as well as the single Reply 25 and PC Enterprises upgrade units, I am very locked in on keeping them. I do have a number of stock 8086-based color Model 25s, but those aren't the level you are looking for (386SX or above). However, we could do a deal on an IBM EduQuest Thirty (IBM 386SLC-25, IDE interface for hard drive and CD-ROM, 72-pin SIMM RAM), being just a slightly larger all-in-one that is a better design than the Model 25.
The Model 30-286 has 4x30 pin SIMM slots, 4MB RAM max (special IBM stuff).
