The alpha 40 would be a great replacement. I have taught a guy to fly with one. As with most ARF's out there it will have everything you need except the radio gear and engine. The engine you had on the last one will work nicely. If you would like to go even cheaper the tower trainer is a very decent trainer too. The tower trainer is a lot like the PT-40.

I have an avistar Elite and it is a really nice plane. If you are taking off and landing on your own then that would be a nice plane for you as well. I think the avistar would be more interesting to you longer than the others will.
