Just to share my experience with the thai consulate in Vientiane:
1. They do not require bank statements to show proof of the 20,000 baht when applying for SETV.
2. Steps have been simplified for those getting SETV - once the guy at the table accept your form and hand you a queue number, you can leave. Only the Non-O applicants need to wait for the counter person to inform you to return tomorrow.
3. Pleasant surprise, ED visa fee for Singaporeans is actually waived. :)
