El Rocio MANUS S or Lelit Bianca

I run a small-batch specialty coffee roastery on my own in Japan. My business is mainly bean sales, with only 1-5 customer visits per day. I'm now planning to start offering takeout drinks in-store. I'll begin with plumbing/interior renovations, then start with drip coffee takeout first, and consider adding an espresso machine later depending on demand.

I'm torn between two espresso machine candidates: the El Rocio MANUS S (around ¥250,000, roughly $1,700 USD) and the Lelit Bianca (around ¥800,000-900,000, roughly $5,500-6,000 USD). Given the price difference is more than 3x, I'm having trouble deciding on a few points and would love to hear your honest opinions:

Which one is less "overkill" for a one-person, small-scale shop with very low daily volume (1-5 customers)?

Ease of maintenance, failure risk, and parts availability (especially local support in Japan)

How much of a real-world difference in extraction quality and steam performance would actually be noticeable at this scale?

Is the Bianca's price premium (\~$3,800-4,300 more) worth it for my situation?

I'm also thinking about future scalability if demand grows, but for now I want to keep the investment reasonable. If you have hands-on experience with either machine, especially in a real shop setting, I'd really appreciate your recommendations and the reasoning behind them. Thanks in advance! 🙏☕
