Reporting in from Penang: got an SETV today. Smooth process. Had to give onward flight and accommodation proofs. He didn't ask for my bank statement but I gave it to him anyway. The official was on the phone the whole time I was giving documents so didn't say anything to me and didn't really inspect my passport which had 2 other Thai visas in it. Pickup today no problem. There were about 20 or 30 people getting visas but wait was minimal. Thanks to this list for the tips.
