I completely agree, your target audience is extremely limited.
In my experience, for many (most?) home games you BYOB and everyone takes turns shuffling and the atmosphere is super lighthearted and play is often loud and drunkenly (albeit super fun).
Then there are more 'formal' games where there is a dedicated dealer, food and booze is provided and the mood is 'quieter', more subdued, a bit more serious... These games usually include a custom poker table, custom clay chips, slot machines, and legit cash drop boxes and POSSIBLY a casino-grade shuffler (although those are QUITE rare).
I started off hosting BYOB poker nights after the Moneymaker 2003 poker revolution and over the years slowly converted to the latter, slowly adding to the atmosphere over time... I was the very first person in Michigan to get the ShuffleTech ST-1000 with flush mount and it worked 'o.k.' except for the LOUD cow-like 'MOOOOooo' noises and the frequent jams. It doesn't hold a candle to the real-thing. I looked HARD at the Shuffle King 2 and the ShuffleMaster for years before pulling the trigger. A new King was the same price as a used
eBay DeckMate - I went with what I knew... That ShuffleMaster Deckmate was the VERY last addition to my setup.
Build a quality, maintenance-free, jam-free, quick, and quiet flush-mounted automatic shuffler - but you are probably 20 years too late as the craze isn't what it used to be. I am the only person I know who would have purchased your shuffler. You might be better off to patent it and sell to legit casinos.
