All I hear is positive stuff about the Quick 36 line. Is there anyone out there that has had a bad experience with one and/or DOESN"T recommend them? Also, are all 3 models good for commercial use or just the samurai or mid line unit? I'd like to get a scag but they are about $1,000 more than an entry level quick. Also about 100-200 lbs heavier at like 470 lbs right? THat's one thing I like about the Quick is that it looks like I could maneuver it easier and get into my truck bed better. I'm about 142 lbs. I'm strong, but dang, 470 lbs is a lot to handle isn't it? But then what about service? ANd how long has this "Better" been in biz?
