I need some help pricing stuff

[NES_Rules]

I'm finally getting around to selling off my extra systems.  But I'm not sure about what prices I should be asking or what offers I should be accepting.  I'm only selling locally because I just don't trust eBay and because I don't want to deal with shipping.  Anyway, here's what I'll be selling.  All systems will have the AC adapter and A/V cords. 
PS1 with 2 Sony non-analog controllers.  I've already posted it as $25, does that sound good?
Dreamcast with 3 Sega brand controllers and 1 VMU.  No idea what to ask for this one.  I've got quite a few spare controllers, should I include 4 in the set?
SNES with 2 Nintendo controllers. I'm thinking $40?
NES with 2 Nintendo controllers.  I'm thinking $35.
Atari 2600 4-switch wood grain with 2 joysticks.   $15?

sounds like decent prices if the systems are clean and the nintendos arent yellowed.
