Bus service to Cambodia?

What is the best bus service to Cambodia...?
I will be traveling there the middle of Sept and wanted some info from this forum..
Please let me know..thanks for reading this ..J :kermit:

i used the Goverment bus in June
from BKK - Sean reap
was great
Have a look on Tripadviser
all the info is there
also get your visa from the internet
saves hassle at the border evisa

there is by now just 1 left: the combined Thai ''govmt'' bus with some Camb-company, running BKk(MOChit) _SmReap, daily, 8.00 from BKK. NO online booking.
The also started daily direct bus BKk-PnPn has been suspended due to very low takings for the current low season/rainy.
On talesofasia.com you can find an overview of about all connect at border links. Without stating from where to where a senseless question.
