I found the X2 great at first but as time went on it was to small . So more power would be good
Gears versus belt. Well if more power then-belt would be better .
I never stripped gears but killed the electronics twice .
As for a different brand with a bigger table i would suggest go for it many a time I found Y axis to small on mine which is why i grew up,
The tilting column i never used but i did have to shim the column from to back to get it squared to the table
The X2 was great for repairing tin toys but once i got into cast engines etc it shrunk
Hope this helps
Cheers
