Need some input by 4:30 est if possible....

My girlfriend is going to get me an early xmas present today - among other things, she is going to add to my poker library. I have ToP, HEFAP, TP (McEvoy) and a few others. I've narrowed it down to TPFAP and SSH. If she can get me both, great. If not, I'll get them both eventually - on a really tight budget for the next 2 months tho.

Which would you consider the more important read?
Primarily, I play SnG's, but I'm working on both my MTT play at lower levels and I'm going to start working on my NL play (.25 - 1$ max for now).

Advice? Thanks a bunch.
