I would definitely say the default wii drum 100% needs modding. That being said, there are 2 other options:
Hori drum. Practically arcade spec. $270. Somewhat overkill..
$30 Chinese knockoff drum. Feels funny to play on since they use real buttons instead of capacitive sensors, but without mods it plays better than the official drum without mods.
If you mod the official drum it's the best value for money, but if you don't want to mod anything I think the knockoff wins.
