Thanks for the input, guys. I think I've reached a decision and I'm going to pull the trigger on an SDS2354X HD with promo bundle before the promo period ends.
As an aside, I actually came to this decision shortly after starting this topic but I was going to use a bank or wire transfer to pay for the purchase from either TEquipment or Saelig. Both of them state that they accept this form of payment but both require you to reach out to a sales rep to do so. I reached out to both via email using multiple addresses from different links on their sites. To date I have received zero responses. Yes, I know I could call them but I'd rather have a communication trail so I chose email. So what could have been a 3-click, 30 second transaction turned into a week of moving money around so that I can actually spend it. PSA: don't bother doing trying to contact these vendors' sales reps via email if you can avoid it.
Unless folks know some reason why I should prefer one of Saelig or TEquiopment over the other, the current plan is to do a normal online transaction using the EEVBlog discount code at Saelig (they don't require talking to anyone to get the promo bundle), which brings the 2354 and bundle to within a few tens of dollars of my original budget. With the promo bundle it seemed like a no-brainer to stretch that little bit extra.
Before I pull the trigger, though, does anyone familiar with Siglent have insight into the lead time on these units? I only ask because I have a short travel period within the window that I'm currently aware of for this. If anyone has any more accurate information it would be appreciated, so I can possibly avoid any self-induced delivery headache. With my luck it's a virtual guarantee that it will be delivered while I'm away. Maybe one way to move up the delivery would be to move up my trip. :-)
Also, I managed to build a working sigrok/pulseview binary for macos, so I'll have a go at getting that working with the HD when it arrives.
Thanks again
