Haven't seen your unit on ebay, but in my humble opinion, you could do better. If the price they are asking is the upper end of what you can afford, be wary... I bought a 1989 31' Excella a year and a half ago for $13.5k from my local craigslist. I got to see it in person. It was decent and ready to camp
in as it sat. I ended up upgrading tires/rims, larger a/c, etc. Have put about $5k into making it what I wanted. The point is, even a perfect trailer of that age will need upgrading, and that will cost $$$... I think Avions are a great trailer, but parts might be more difficult to find and expensive if needed... Just my thoughts, good luck and safe travels!!
