Is $300 too much for a used iPhone 4S 16 GB?

I just bought a used iPhone 4S 16 GB. It is in excellent condition, and I'm happy with the phone. Did I pay too much though, or is this what used iPhones go for?

Added (1). I saw the Verizon, Sprint, AT&T, and Verizon ones were going for $250. I'm going with Metro PCS, and they told me I had to get a T-Mobile version, or I would get stuck with 2G speeds.

Added (3). Sorry for the double post. I only clicked the button once, and it posted twice.

Depending upon the model and the added apps.

Yes it is. You can buy a phone on the street here all day long for $20-$40.

Not bad but I've seen mint condition ones for $250

That's actually a lot… Yes, it is.

… Especially with that small gig amount. Plus it's used…
