They're around 50 or 60 dollars with a one year warranty. There are some models that may be more than that but most are pretty inexpensive.
Ps2 and the ps2 slims go for under 100
Honestly they aren't that much. I think the last time I was there they were selling one for 180$. I think it all depends on how well kept the system is that effects the price. I believe they go off prices online sometimes but majority of the time the prices for systems aren't overly expensive.
