This one I purchased on Reverb for only $200! It came with stock switches and keycaps. The downside is that these 40 year old switches were completely unresponsive, the AC power cord and case were beat up too.Â
I would recommend only to do follow through with this cleaning if you have 2+ hours of time to dedicate. It's important to get this right the first time to avoid having to tear it all apart again.
