We Sadly don't get Tacony products in SA, but I will say I agree with Dan on a few points,( and while we are friends we have very different tastes in vacuums )
For one I am very big on buying stuff that is made in the country you live in, it is after all supporting the economy you live in.
Second I have never understood why so many people find sebo's so wonderful, I have had every model they have made and still own my Felix and G1, The build quality is ok but no were near as great as people make out, There performance is OK but not fantastic, and they are missing many convenience features that others include.
The x4 was my least favorite sebo only which could never get the height right from new.(I owned 4 from new all the same) If you don't believe me on this rub some sebo dry carpet cleaning powder into your carpets and use your x4 to clean it up and vacuum your carpets every day for a week, Now go down to your local sears or walmart and buy a $ 40,00 Bissell power force, Bagged or bag less it doesn't matter, Go and vacuum your house again and see what the x4 left behind because it can never get the adjustment right. The bag will be full of powder.
Out of interest I did the same thing with a x4 and better G1 with manual height setting, I dry cleaned the carpet in my one test room at my factory, vacuumed every day for 5 days with the X4 then vacuumed with the G 1 same machine but without the electronic height adjustment, One bag filled 3/4 with powder the x4 left behind because it simply can't get to it.
I was equally unimpressed with the d4, Its build quality was not on par with machines half its price, Its PN was big and bulky compared to the competition and it didn't have a switch ( which I see is been remedied ) on the handle.
The Felix is one of my favorite sebo's, It cleans really well but again falls short in the convenience department, the hose is a joke and it still fails me that a machine made in a country that has 90% hard flooring in homes doesn't have a On OFF brush button on the handle or upper body( at least it has one unlike all other sebo uprights ) Hepa filtraion is not even standard for that price either.
One last point they are prohibitively expensive to repair if something goes wrong, More expensive than many machines costing twice there price like Kirby's and Rainbows.
My opinion, If you want a good vacuum for carpets don't buy one designed in a country were the average home has none.
