I'll have to recommend Form Master from Code 5 systems.

I can't vouch for the customer support because it is one of the few modules that I have never needed any customer support for.

Which module you choose would depend on what you are looking to do.  One other thing I have learned is that the easier it is to use the less you are able to accomplish with it.

That being said I would first look at the core User Defined Table module to see if that will do what you want. The UDT module has come a long way in the last couple of years plus it is free.  Next I would look at sqlgridselectedview from www.tressleworks.com. This module has also come a long way - V4.0 is still free and the new version 5.0 is only $10.  The next easiest to use would indeed be Form Master. And if you want more abilities / features next would be Xmod.  Xmod has always been the best selling module on www.snowcovered.com due to it's extensive features, ease of use, and great support / documentation.

Hope this helps
