To the OP (I've only read Page 1): For what you're asking, G1 Soundwave is actually your best bet. If you want more posability, you'll have to sacrifice the tape storage thing and go with Music Label Soundwave. Titanium Soundwave is oddly shaped, and has better knee and hip articulation (he's the only one I have, personally), and only holds the Laserbeak he comes with, has weak telescoping legs, and is just kinda odd all around. My personal opinion is that you forego the tape storage and go with ML Soundwave. I wish I could afford one. I have a little caveat to that last statement, but it's not relevant to the thread.
thanks man.. I"m now leaning towards the ML Soundwave.. plus HLJ has a sale on it aswell. I still don't get why Spark Blue is more expensive than the Black and White one.
I just recently won an auction for ml soundwave where the guy offered the winner the frenzy/rumble headphones for $34. ended up getting the whole lot for $90 shipped.
