We're in need of at least two of these, more if possible, but I've yet to find them online anywhere at least on the english sites I've looked at. Any secrets to finding these, or are they really as scarce as they seem? We have a rather large layout that's really suffering from power problems (we have 20+ engines, 50+ switches, 5 signals, bumper lights, a turntable, and the cargo crane all running off one transformer) and we're starting to get desperate. Any pointers in finding these would be very much appreciated!

They seem to be in stock at Marklin so you could order one from any of the shops.

I use these and I know many of the forum members also use them.

I also use the LDT boosters. I buy the kits and save even more. They are not difficult to assemble, but if you are not familiar with parts identification, the instructions may be hard to follow. They are not as clear on parts ID as the Viessmann kits.

These boosters are favourably priced, and they can be connected to the 6021 central just as the 6017, including shortcut protection. The smaller version can be bought as a kit, but both of them are available as a finished booster as well.

By the way, Tams have a description on their webpage of how to connect the booster directly to the computer and not through a central unit and interface. But you need to install DDL or DDW program to do this.
