After reading this thread and others at pianoworld, I picked up a Studiologic SL73 as a travel piano about 6 months ago, and it’s been great.
It has a Fatar keybed with TP100LR action–weighted but graded, so similar in that respect to a true hammer action. Best things about this keyboard are:
- weight/size/durability–with pelican case it comes in at 47 pounds (so no overweight baggage fee), and has survived about a dozen airplane flights.
- price–costs about 20% of a top end stage piano, so not quite as much of a disaster if something does get damaged during transport.
Cons are that it’s a midi keyboard so one needs to travel with a VST, and, supposedly it’s difficult to get Fatar parts if something goes wrong.
The action is relatively heavy which takes a little getting used to but is great for practicing, and I’m very happy with it.
