I have a friend who's willing to sell me his, but neither he or I know a fair value.

Screen Fabric Specifications:
Model: Studiotek 130 (Snap on Screen)
Image Dimensions: 52" x 90" (4:3)
Surface: StudioTek 130
Format: Video 16:9
The screen is described in gently used condition.

3- Questions I have

1. MRSP is about $1900 right?
2. What's the fair price I should offer him?
3. What's the cheap Ukrainian price I should offer him :)
