I'm currently in the process of trying to get a new job (not easy in today's economy, even if we ignore all the basement and bedroom-based "designers"), and the most promising opportunity will require a great deal of data merging next to the work I've been doing in the past.
Normally that's not a big deal, but this merging requires connecting to a remote SQL database (MSSQL or MySQL, not sure which) for a project I'll need to set up. So I'm doing a little homework in advance to make sure we can get right to work if things go through.

Thanks to an old post here on the site I found TeaCup's DataLinker and Cacidi's LiveMerge, but there's quite a big price difference between the two, even with TeaCup's ODBC add-on included — €373 for TeaCup's software vs. €990 for Cacidi's — while they both seem to promise roughly the same… though I admit I've only skimmed the descriptions so far.

Does anyone have experience with these, or other similar plug-ins/programs?
Are these good or should I be looking at something else? I'd like to keep using InDesign, but if there's a better solution for printing data merged documents (anywhere from 1500 to 5000 'records' at a time, 4 to 6 per sheet) I think we'd be willing to consider it.

As far as I know we'll be using CS5 (or 5.5) as that's what I was using until recently, but I don't know yet whether it'll be on Mac or Windows. So ideally the solution we end up with should be available for either platform.
