I have had a look at your items and could give you a rough valuation I am sure if I am out buy a few quid someone will pull me up on it but here goes.
Millennium falcon I am going on this being 100% complete with training ball and ramp struts £175
Slave 1 £120
VME Looks incomplete £20
Tri pod laser cannon £25
Radar laser cannon £35
Rebo band £120
Loose speeder bike £25
Loose one man sail skiff £30
Loose MTV-7 £5
Hope this helps if you decided to sell as a job lot I would be interested but wait out for more valuations before making any decitions.
I did see the figures but the prices are little bit all over the place I could value them but I would do the at the prices I would sell them for so would probably differ from others but the lot as a whole are worth around £800 in my opinion
Stubbs is pretty much on the money with his valuations but I would probably stick the Rebo band at £150-ish as the blue on Max looks pretty sharp.
I'd be interested in the Slave 1 is the box is in decent shape.
