I initially thought the same thing, until I finally bought one.
It is a game changer.
For the concerns…
1) It’s loud - I took a cheap $90 IKEA cart, cut a hole in it, and put the flush mount in. I put 3 pillows that surround the shuffler in the shelf inside the cabinet. The sound is a minimum. My table doesn’t even notice it when running, and some sitting at the table were shocked to find out it was even running (I mentioned to them some don’t like it because of the noise).
2) I usually sit next to the shuffler and it’s a self dealt game. When the button moves, the used deck gets handed to me and the shuffled deck is dealt. The vast majority of times (>90%), the second deck is shuffled and already placed in front of the future dealer ready to go before the current game is finished. It has sped up our hands per hour and decreased the headaches of continually shuffling when playing dealer call it games, especially 3-5-7 and guts (3 card poker).
3) Yes, it can be pricey, but I stalked different places online and eventually went with a dealer that didn’t charge sales tax and had free shipping.
4) Jams - I’ve probably played over 1000 hands with mine without a single jam. I use Copaq cards.
5) My regulars love it. Currently
@alecnetwoodworks is building me a custom cabinet with sound dampening tiles in it, along with a shorter profile, but the ikea cart is very economical and works great. I will try to get a picture when home. I installed 3 cup holders on top of it too with a locking mechanism in them. It gives me peace of mind when I have a drink on it. I issue the cart for my iPad that controls the AV system in my basement, and whatever beverage I have, usually a yeti full of coffee.
