Hard to answer that. The more disposable cash you have on hand, the higher a "reasonable" price can be. The less cash you have, the lower that price must be. The only real answer to a question like this is that if YOU are happy with the price and don't feel like you got ripped off then it was a fair price.
The "going rate" in your area may be more, or less, than what you'd pay. If you're asking what the going rate is in your area, you'll have to let us know where you are so that someone in your area can chime in.
