#1 - Single modded, salvage the 20% and then +5e if the tsaff stays behind.
#2 - ~5-10k, I'd consider salvaging the 20/20 sundering and selling for 6-7k.
#3 - ~5k.
#4 - ~3-5k.
#5 - 60-70k, still quite popular.
#6 - ~30-40k maybe, unsure on this one get a second opinion before selling.
#7 - Salvage the 20/20 and sell for 6-7k.
