anyone has any experience with SAP?

i'm currently a programmer in a local company. with so so salary..
it's a small company, so not much bonuses and benefits..
i had been working for this company since i graduated for 1 year.

so, should i step my foot in to SAP?
as i know, SAP can't be mastered in a few months..
it's a long term investment.. and once i'm with SAP, my whole working life will be only doing SAP.. if not whole life, it also will be a long term..

so, any sifu here can give me any guides whether should or should not stepping in to SAP.

yea.. actually i got this offer..
i don't mind if bonded for 2 years..
but.. venturing into the SAP world.. is it worth?
