The current method of separate modules, where we can pick and choose which options to use together gets my (very strong) vote!
Jamming them all together will just create unneeded bloat for some.
I would still pay a "forced" bundle price, if it gave me the option to use just the modules I need... and maybe add one or more of the others later.
I'm amazed at the quality of product/s that one (I think?) developer has produced and offering for a low - as Chris says, almost impulse buy - price.
Keep up the good work and bug squashing guys!
