friends of ours found it much cheaper to use a company over the border in Germany - they came and installed and everything for 20% cheaper than Zurich and the company handled the tax issues...

I'm curious, do Ikea have an installation service ? My husband has put together many Ikea kitchen units for a science laboratory, which incidentally is a really good use of the Faktum system...but it's a lot of work...and you have to drill and bolt it all together and get the bench tops cut down from 'standard' lengths...
