I live in Zurich (Switzerland), there‘s a great synth repair shop here. I once had him fix a Roland JV 1000. The keys were badly glued together and many weren‘t working (epoxy resin issue) and I wanted to use it for piano practice and as my master keyboard. Cost me about 400$ (which is more than I payed for the synth) but I don‘t regret it, still works great :)
