New enthusiast 3 chime vs 5

I am new to the horn hobby and looking to buy my first. Will I be feeling inadequate if I buy a 3 chime Nathan? I would hate to buy it then be unhappy
I didn’t buy a 5. Also does anyone have anything for sale? Let me know! Thanks

Believe it or not, a K3 is actually louder than a K5 decibel wise
The two extra bells on the K5 are actually tuned to cancel eachother out, which makes it more musical, but it isn’t any louder.

I was able to pickup a K5LA for a great deal. My next question is should I use a 1/2 or 3/4 air line for it. I already bought a 3/4 hose and 3/4 solenoid. What are your thoughts?
