New PODxt Clip...Uberschall + 5150 Model

Does it worth to buy Metal Model Pack? And Bass Model pack?
I'm thinking to buy them but I'm not sure.

I have both & use them exclusively for high-gain guitar tones & bass tones; The Metal pack is worth it just for the Uberschall & 5150 amps. I'm thinking about buying the pedal pack, because a few of the patches I've checked out here are using pedals I don't have.
