Just an FYI, I bought two Toaster 4000s and two Video Flyers for what you are asking for your Flyer, though my Flyers didn't come with hard drives.
I just saw a set go for $150 (Flyer & Toaster4000) on eBay that was snapped up pretty quickly.
I know pricing can be difficult with this stuff and a lot depends on when you are offering yours and when someone is specifically looking for what you are offering.
