Choosing database between MSDE and Access

hi,

I need to choose a database based on the following criteria (using .NET app):
1) a light but fully functional database, preferably with the support of store proc and constraints, less than 8000 transaction a day.
2) portable or the database can be export/import very easily
3) reliable and stable
4) least maintenance

I have two db in my mind, Access and MSDE?
Does anyone have some hand-ons experience on the above two? Or any other better suggestions?

Any advice is appreciated.

thanks,
