SS planer is worth about $400-500 used, jointer about $100, band saw
$150-200. This is based on watching ebay selling prices from sellers
who box and ship, not sellers who insist on pickup (which severely
depresses selling prices).

Basic SS units are not hard to come by and values suffer as a result
but some of the accessories hold value and the SS is an interesting,
accurate and versatile tool. The system makes lots of compromises
in terms of capacity and speed of setup. The quality of manufacture
is excellent for a hobby machine.
