I know the situation your in and even though its great to get feedback on pricing what they are worth etc, sometimes it turns into an all out frenzy.
Machines are so different in condition AND people are so different in what they deem or what thye would like condition wise.
SO its important to figure out where you want this pin to be when your done (condition, leds, etc).
Some people buy for book value play them and thats it. Me personally I plan to keep them forever and they will eventually be top condition.
SO here is my 2 cents:
- When you price it factor in everything you plan to do or not plan to do. I have purchased machines for a great price turning down better of the same but higher price only to exceed the price in fixing it up.
- I bought a WW for a decent price and only put a new ramp on it. On the other hand I got a Diner for a fair price and dumped a $1000 plaus into it.
- Prototypes do not factor them into the price. I have a proto Diner and big whoop. Who cares.
- CPU upgrades are worth nothing. All my system 11s are original and work great. I have a Judge dredd with a new pinled expensive main board. Actually I hate it with that board. Wont get into details now.
- I would pay $2000+ for F14 if I knew I did not have to spend anything more on fixing it up.
Same with ES.
And the main thing is how you feel about the price. It does not matter if you get something for a $1 or $10000 if your not happy its not worth anything.
People who hate ES will balk saying $1000 is too much but thise who like it will say $2200+ for a great cond one.
My experience my great deals never turned out to be great after I fixed them up, the expensive ones seem to in the long run been worth the extra up front.
Good luck, both are cool machines.
