TBC machine needed - DATAVIDEO 1000, Fix my AG or... a DVD recorder?

I heard a good way of doing a passthrough tbc is using a dvd recorder such as DMR-ES10... would that be better then using a specifically DATAVIDEO TBC1000 device?... how about using my AG-1980 which has weared heads but can be used as another passthrough alternative... you tell me! and I know there are differences in different TBCs machine but what would be the best of all 3... know that I'm gonna be using my SLV-r1000 as the source as it seems it has better playback quality then my AG but without TBC it doesn't do as great... I hope to have the best of both worlds soon... my SLV + TBC = god who knows...
