can anyone tell me the drawbacks/shortcomings of the MPC 1000 when you compare it to the 2000XL or 2500 ?? ??

I have a 1K with jjos, upgraded pads and pad sensors it is awesome. I bought a 2kxl for cheap thinking it would be awesome, i learned to use it and it is slow to save, slow to load. I use my sp303 and 1k almost exclusively.

i have a 2500 w jjos, it's the best. also, a 1k w/jj is the EXACT same thing as a 2500 w jj, just slightly bigger pads and 2 more sliders that i don't really use anyway.
