I have a 20 tub ARS 8018 and so far it's pretty nice. My only gripe are the windows in the tubs. The glue job was kind of shoddy so I ended up drilling 6 holes(2 for each long side, 1 for the shorts) and zip tying so I wouldn't have to worry about them popping out anymore. I don't mind the powder coating really. I'm in hot/humid/salty florida so used to living with a bit of rust. I think my next purchase will be a Freedom Breeder 66-6. Mainly because the 66-6 tubs are a fair bit larger than the biggest model ARS offers.
