It is a reasonable price for a working game in that cab, but it isn't a stellar deal.
I wouldn't advise against buying it, but you have already said that you are out of cash, so don't sweat it -- there will be another deal.
EVERYBODY says that there aren't any cabs available near them at first. Frizz used to moan and ---smurfette--- about how there were no cabs in BumbleFark IDAHO ... and now he has to turn them away.
Having said all of that, a cab is worth what someone will pay for it and if you buy something and are happy with the purchase, then be happy with the purchase and don't worry if you could have gotten something for cheaper.
