SX 5'ers are really inexpensive.
This, seriously, I love my SX 5 string, I don't understand why people have such a fright toward 5 strings, unless you have some kind of medical condition (or your just really stubborn) you'll get used to the small added with of a 5 string in no time
and BTW the neck on my jazz SX SJB-75 5 string is not baseball batish at all, its actually quite shallow and sleek.
