I am new both to the hobby and to this forum. Please be kind to a newbie

I was first introduced to ham radio during a high school program I did at NASA Glenn. Recently, I was reintroduced by a neighbor who I learned is an old pro. Through him, I learned of the Radson brand. As it is a family name, I would love to be able to purchase one -- working or not.
Is it acceptable to post a WTB (Want to Buy) ad in the classifieds?
If not, what are some other places you would recommend? I mean, it seems eBay has them occasionally and I will keep checking QTH, but recommendations are certainly welcome

Thanks everyone! I can't want to be back to learn more about this and the hobby in general
