In case anyone reading this is from Massachusetts or nearby states and hasn't been to the Round 1 in Taunton (Silver City Galleria) yet, here's a short review of the cabs currently there:
2x SDVX III Gravity Wars (3.5?/5)
* Left cab's BT-B gets stuck, right cab's VOL-L is stiff af. Both have caused me undue failures in Skill Analyzer, but it's probably just me because it looked like the regulars were dealing with it just fine
2x M?SECA (5/5)
* Both in great condition
1x GITADORA Triboost (D 4/5, G 4.5/5)
* Floor tom is kinda borked imo, everything else is great
* Machine positioning is back to back which is dumb
2x Crossbeats REV (5/5)
* AIME available, left cab in great condition, and I can assume the same for the right cab.
2x IIDX copula (4.5/5)
* Largely in perfect condition, the turntables are stiff to me but I guess this is the AC standard now?
1x PIU Prime (4.5/5)
* Pads are great but not perfect.
1x PIU Infinity (

/5)
* Was borked when I went so idk.
1x pop'n music 20 fantasia (4.5/5)
* Buttons themselves are perfect, the only problem is no eamoose (for obvious reasons) and being on an SD cab with its blah audio and video quality. If you don't care, consider this a 5.
1x DDR X (4/5)
* Pads are mercifully not crappy as but the screen is gross. Obviously no eamoose. Also, still a NA (Betson) cab.
1x Music Gun Gun 2 (

/5)
* idk how to rate this because I haven't played it much but it certainly works
1x Taiko no Tatsujin 13 (4?/5)
* Didn't play myself but it looked fine when my friends played it.
