The Yamaha DX7, the quintessential digital-replacing-analog synth, cost $2k USD in 1983, not $4-5k. I can't speak for what that cost in Euros (which didn't exist yet) or with import tariffs in an unspecified country. Today you can get one used for $500 USD. And while analog is and was more expensive, today you can get a Behringer Deep Mind 12 for $900 USD new and it sounds fantastic.
Meanwhile, Teenage Engineering is selling a tiny digital synth for $1,200, which has less functionality than iPad. I find it hard to take serious as anything other than a design object but YMMV.
