Not to slam you kid but, I believe single V-5 i-Opener is still worth more that all you have listed together...
The Used V770 is only worth about $35-$45 now....I picked up one new in box (32MB) at HDNW for $99 over a year ago....
The 810 HDD about $20-$25 max. I just bought a 1.3GB for $29.00 and a 2.0 GB for $39.00 like new.
The Cybiko? Used guessing at $50-$75 Priced $99 @ OD new...I'm not really into these...
So with The three items you have listed estimated used total fair market value @ $105-$140 MAX depending on the condition of your parts.
I'm a well experienced new and used computer parts buyer/trader in my area and know what most computer parts fair market street resale values are here.
Like I said I'm not slamming you so don't take it personal but I think you need to up the ante a little bit more...
or try your luck on e-bay...
