Shimano Deore SGS T610 "10-speed" rear derailer, this is a DynaSys model and won't - I discovered this the expensive way - index your 7/8/9-speed stuff but is just dandy with friction. $30 shipped
Box o' shifters: Suntour XC Pro thumbies, "hard" and "soft" 7 index, I got the soft to index an 8-speed Shimano rd/cassette but no promises.
Another lower-end Suntour rear and a vintage 9-speed-era Shimano XTR front clicker. Priced mostly to cover the XC Pro shifters, the others are filler maybe you can use someday. $30 shipped
Or take the whole schlamozzle for $55
