What are the best walk-in options for applying for the DTV visa from Jakarta, Taipei, or Laos?

Walk-ins still available in Taipei, but not for much longer. They move to the e-visa system reportedly on November 19.

Jakarta is still allowing walk-ins for the foreseeable future, but get there soon as they'll be making the switch too, though it's not quite clear when.

Laos (both consulates) require an appointment, but statements MUST show at least 3 months worth of 500,000 Baht parked.

I would recommend applying in Jakarta, they sound like they're the easiest. Taipei is OK, but fussier with financials. If you have a job and money is being paid into your account and you can document everything properly, Taipei is fine...however, I have the feeling neither Laos nor Jakarta will scrutinize your transactions.

Laos probably won't care how you got access to the 500K Baht as long as you can show proof the funds have been sitting in your account for 3 months or more.

Jakarta and Taipei don't care when the funds were transferred.

yes, Taipei still available for walk-in. But they will be changing to online application in Nov.

Got mine at Jakarta. 500K was in my bank account for 1 week.

Laos is walk in via an appointment. Jakarta and Taipei are direct walk ins. You need to produce 3-6 month statements final balance of 500K THB.
