My sunday crappy weather flier is my old trusty Hobbico Skyvista low wing. I love that plane! Hauls around niceely with a 40 sized engine and is easy to fly. They are hard to find now. H9 makes a $125ish Cherokee thats very similar.
hard to say for around $100

I would look at Vmar stuff as well. Just make sure you do some reinforcement of the importnant sub-strtucture joints and you will be ok.
Also try the Marketplace here, there are some pretty decent deals floating around.
