@Botakchek,
I did this change of bearings on a LIKE 200 last year. Material was around €80,- for SKF roller bearings, which replaced those ball bearings. So, $200,- for this job seems not to be unreasonable for me, for you have to extraciate the whole front, handlebar, etc.
Also extraction of old bearings from your frame is tricky. And, if you want to sell it ( let alone safety thoughts), no one buys a scoots with broken fork bearings, except very cheap.
