Info: humble budnle & undrgrnd bundles

[Rising Night Wave]

yo. hi.

i am interested into buying these two bundles:

1. Mega Music Maker Black Friday Special bundle @ Humble Bundle ... 54 packs for at least 25.37€ and
2. The Bundle 2 @ UNDRGRND ... 60 packs for 68.78€

now what i want to know is:

does anybody own any of these mega bundles?
because i would like to know:
- how well are WAV samples named in these packs
- and why in the hell does UNDRGRND's mega bundle 2 not includes REX2 files ?!!!

WTF for UNDRGRND! ... the bundle 1 contains REX2 files meanwhile bundle 2 (which i mentioned) does not have these REX2 files. and snce i am using Reason DAW ... it would be more than cool and welcome that this Bundle 2 would contain these REX2 files. f**k & damn!

so the additional question is:
would buying UNDRGRND bundle 1 be better choice? it lacks 30 packs in comparison to bundle 2.

god damn it!
