Any comments on speed and robustness of RH Server running on Windows 7 and using SQL Server Express?

Hi. Can anyone comment on their experience using RH Server on Windows 7 and using SQL Server Express? That is, is it stable and fast enough for delivering Web Help Pro documentation to support occasional viewer browses. (We would have approx 250 customers who would occasionally access the HTML docs that support our software.)

Our company is not keen on spending $s on Windows Server and an MS or Oracle database.

Thanks in advance.
