I'd bet that the second one you posted Dave, could be fixed up.
as long as the input hardware of a lecroy scope is fine, most of it can be replaced with other stuff if you can acquire the drivers (being PC based)
Pity the first one's bottom board looks destroyed...
EDIT:
PLEASE buy the second one Dave, It would make a great teardown video... maybe see if you can resurrect parts of it even? It could prove interesting. Worst case, put it back on Ebay again.
