Pertti,
Yes I suggest GUIDs. I already hit the problems of integer keys myself and solving them was no fun ( $#@@!#!ed myself a lot why I didn't use GUID from the start).

It's not pricey compared to what it offers. Express version is for free, Pro, enterprise and BOS have different price levels. If you think you'd deploy a BOS solution to a big company (enterprise level) it'd pay much more of its price in first application you sell:) At least get express and contact the representatives. You'd be amazed with support and professionalizm, getting that much help though you only have express etc.
