When I was a teenager I had a great time with the Yamaha DD-55 plugged into a practice bass amp.
I bought a DD-35 for my kids and they seemed to like it enough so then I bought a new DD-75, with the nicer beater pedal, but they didn’t use it much. Shipping it to the reverb buyer cost $80
If memory serves, the DD-55 was just as good as the DD-75. Functionally the same in sound and pad feel and build quality. (Good being a relative term because the HH would trigger randomly if I hit the share hard enough in both machines.)
Oh, and I recommend rubber tips for the sticks. Really cut down on the noise of the hits, which was loud enough to overpower the internal speakers
