If anything hold on to it get your money right and get a used 1k.
At this stage in the game the 2k and 2kxl are the worst MP's.
Not old enough to be classic and not new enough for modern workflow.
After all these years of owning MP's here's how I rank them.
1. Maschine (w/ Komplete and Miroslav )
2. 5k v2
3. 1k w/ JJ and new pads
4. 2500 w/ JJ
5. 500
6. 3k
7. 4k
8. 60
9. 2kxl
10. 2k
It is all his/her preference, so I don't think this person should be dissed that much (although I completely disagree with the ranking...) I think Sovereign likes software solution better than hardware (nothing wrong with it), so I kind of see why he/she ranked MPCs that way.
MPC-500 is known for its bug-ridden OS. I've read a lot of horror stories with 500 on MPC Forums.
MPC-5000 and MPC-500 were probably entirely developed at Numark / Alesis company. (The original Akai company completely folded in 2005. (You might see AKAI branded products still, but they have zero connection with the original Akai company) MPC-4000, MPC-2500 and MPC-1000 were developed by the original Akai Professional.)
Most of used MPC-1000 suffer pad problem (faulty pad issue is the main reason why people are selling it...) Now, it is quite possible that old MPC-1000 and MPC-2500 are well-build than the current ones.
Un-related link, but I found an interesting e-book:
http://www.amazon.com/Akai-Professional-ODonnell-Professional-Herewith/dp/B00081SA94MPC-60 and MPC-3000 were both manufactured in Japan. I think that really contributed the solid feel of both machines.
There are never-ending debates regarding sound quality of MPC-3000. I think the reason why MPC-3000 sounds better than 2000 has a lot to do with power supply. I think that those older MPCs have better power supply than the later MPCs. Correct me if I'm wrong, but I don't think switch power supply is used in 60/3000.
(Un-related side note: old Numark and GLi DJ mixers were made in Japan. They were great, solid mixers.)
MPC-2000 classic and 2000XL are cool machines. If XL had 2000 classic's jog wheel, it would've been really nice. (I have XL with a brand new rotary encoder from MPC Stuff dot com, but it does not feel great.)
Back to the original question, it is not a bad idea (at all) to swap to 2000 Classic, but make sure all pots, switches, pads, storage device, and LCD screen work as it should. Real weakness of 2000 Classic is its limited storage options (floppy and SCSI only) and lack of folder support. The feel of jog dial is really awesome, jog dial on XL sucks (even with newly replaced one!) It is a bit hard to compare those two MPCs, but I'd pick 2000 classic over 500 any day.
