If you could own any Bemani cabinet, which would you choose and why?

For me, it's a 50/50 between MUSECA 1+1/2 and SOUND VOLTEX III: GRAVITY WARS, but if SDVX IV: HEAVENLY HAVEN turns out to be wonderful like the previous ones, then it's a no brainer for me. Although MUSECA has a somewhat recycled song selection, I find the gameplay interesting and addictive (but tiring, especially level 14/15 songs!). However, my first serious addiction to a Bemani game was SOUND VOLTEX and the gameplay never gets stale for me. I've probably spent well over several hundred dollars on SDVX alone. Both of these games have very high skill caps so I know I'll be improving a lot just by having a cabinet. Just watch the latest KAC.
