I'd personally recomend stepping up to a full-fledged trainer. There is a good list here: http://www.rcuniverse.com/forum/m_4537845/tm.htm

If you really want to stay with an RTF electric foamie then maybe something like the E-Flite Apprentice would be a good idea.

Of the planes you mentioned, the Parkzone T-28 is by far the best. Keep it on low rates and you might do just fine with it.
