I agree very much with that.It'll make a good starter trailer. At 15 I'm sure you're on a budget and this fits the bill perfectly. It won't last forever but you'll probably want to get something larger in a few years anyway. Use it for a couple/few years and then sell it for what you paid for it.
In addition, have you considered used trailers? I paid $500 for a well-used 6.5x16. After about $800 and a lot of elbow grease, I got her looking and functioning very well now. It's a very nice trailer, but it needed a lot of work, and that's exactly what I did.
