took lessons for about an year and a half, developed a decent consistency and variations of rock and funk grooves. didn't own a drumset while i was still takin' lessons so little practice made me an average pop rock drummer. got a drumset now so catchin' up on the real drumming aspects finally.
i'll say lessons are good, since you learn correct technique fast, with self-taught stuff, you might pick up a bad habit? i watch instructional videos over n over again few times to make sure i'll be practicin the right technique.. but drum lessons in sg expensive la, at least 2 years back ^^
