JTFM will soon be releasing a E-25 based SPAAG (with the Kugelblitz turret & ammo trailer), it's finished and very nice it is too. They also have a 38D in the pipe, with two options, mounting either the L48 PaK40 or a PAW600 in a simplified PzIV turret (the upper hull/deck is not yet completed).
I've been looking forward to the latter for a while & the SPAAG will also be most welcome.
