This forum is the pro and con, Xrad built a Tamiya hulled H/L Jagdpanther. I purchased the metal lower hull for a King Tiger from Tamiya America for 8.92 us. I did this so when the new Porsche King Tiger does come out I can have a metal hull.
Use the search function and you may find several half breed builds,keeps the cost down yet you have a solid foundation.
