You will have no problems finding a quality used one for under $25 and should be able to find a fresh decently equipped one for under $15. The resale on those things drop faster than just about any other kind of vehicle and most people that have them just put highway miles on them. Several years ago, I bought a 2 year old E150 with about 30K for under $10, but it wasn't a high top. It pulls as well as an F150 and have driven it on 5000 mile long road trips with a small camper in tow without a problem. I have pulled the wakeboard boat over 600 miles in a day with it and it is a stable pull, and it will climb hills but it fades on the steeper ones.
From a practical standpoint they are more functional than 4 dr trucks. Way more comfortable for passengers and your gear is easy to keep stowed and locked. Not that this is a big negative, but my teen sons would probably rather walk to school than be seen driving it. Ahhh the vanity of youth.
