I made my first visa run to get an extension on my thirty day tourist visa. From Ban Phe the border run cost me $50 USD with most of that going to the Cambodian government. It was a hectic and expensive day with 1100 Baht for a Cambodian visa, a 300 Baht same day departure tax (Cambodian), a 100 Baht SARS health check (also Cambodian), and a couple hundred baht for local transport. By far one of my worst experiences in Thailand and something I?m not looking forward to doing again in 30-days.
