Retail price is $600 for the newer Pro 3T.
It has a titanium driver for the rotary speaker... and a built in 40 watt amp with tube pre amp.
The portable Leslie 303 also has a low rotor simulator... but has a 12 inch speaker built into it's cab with two solid state amplifiers. Weights 110 lbs and costs $1400.
Personally I believe the low rotor simulators sound better for steel then the older Leslie 147 and 122 revolving bass boxes.
I've never played through a Leslie 303... it may be worth mentioning that Leslie does have a patent on it's famous sound.
