Price check on some old hardware. R4, AVA821

[DaveF]

In the continuing saga of Dave is cleaning up.

What is an R4 worth? It's doing about 7.5T poolside.

Also is an Avalon 821 doing about 8.5T poolside worth anything?

I really can't get a feel for pricing on 1 off units like this. Heck, what I feel are great deals on some older equipment are not getting any hits.
Figure they are going to be US shipping only due to size / weight / cost.

The other part of it is, there is a cost to going to the DC to pick them up so if I have to spend 2 hours driving there and 2 hours driving back is it really worth it for $80?

Thanks,
Dave
