The new makes are visually not too much, but the devil is well known in detei.
Technically, the new system meets exactly what you need, from built-forth that is doable for a skilled worker, but the price is just already a number of its own.
I think with 100 less would be the part already paid well, but that's just now time when you have a name in Germany, you can calm the production in some low-wage countries produce and then leave here very expensive Sell
I've also looked at what the Bauhaus and eBay, but what if there after one year something breaks, well then have fun times Order of spare parts !!!
End result is stop, be quiet and pay what the manufacturing will have stop !!!!
