Convert Access to dot net

[homer]

I am looking for ways of converting MS Access application to dot net.
I found several websites saying they can do the job. I’d like to here any
recommendation from the group.
Here are the ones I found, and my concerns based on my preliminary assessment.

Greenwich Financial Modeling Inc. (http://www.gfminc.com/)
They had been on Access journals years back, but their latest news on the
site was dated 2001, and I could not get a email reply from them. Are they
still in business? Their product only converts to VB6.

MicroTools(http://www.microtools.us/default.htm) Their product is cheap, and
their site looks less sophisticated. My big question for them is can they do
a decent job.

Diamond Edge(http://www.diamondedge.com). Their products are more on
converting to Java platform side.

Thank you in advance for your help!
