copping leslie tones

It's big, but give the H&K Rotosphere or Neo Ventilator a "whirl"...lol.  They are the 2 best sounding leslie sims available, IMO.  I've also owned (and sold):

Line 6 Roto-Machine
Option 5 Destination Rotation Single
DLS RotoSIM (not bad at all)

I never bothered with the RT-20, based on reviews and my experiences with the RE-20 Space Echo. Their bypass tone does suck.  I never bothered with the Korg because they are enormous, and hard to find.

Just whatever you do avoid the dunlop rotovibe...they break! I had two, both broke within a month.

Hmmmm I really like my RT20 and the light show it emitts....

You could always try a MXR Phase 90 or TC Chorus (any decent chorus really) with the speed high up.  Also, I hear the Option 5 Destination Rotation is a nice rotating speaker emulator.

I actually use a Rocktron Xpression in the effect loop of my fuchs ODS.  Their Rotovibe has a top horn and bottom horn speed adjust to really tweak it...gives you that nice swishy sound.  Verbs aren't that great but adequate.  Delays (2) are great and programmable so you get different delay times/feedback for each song.  Helps if your drummer plays at the same tempo each night which fortunately ours does.

No way Mang!     Really, the RT-20 is the only Leslie sim besides a horrible Rocktron (barfffff  ) that I've tried.  I like the tweakability of the RT-20, trust me there are some wonderful sounds in there if you tweak it right.  Also, the genious and SUPER usable dual pedal format allows you to essentially create two awesome sounding leslie setting AND you can set the ramp time between them!  I love the light on it too, it's a real eye catcher and makes non-guitar players ooooh and ahhhh asking "thats pretty, what does that one do?"     The first time I ran it in stereo through the effects loops into a big 4x12 cab + two amps it was such a huge sound...  It allowed me to cop a passable Joe version of "Tea For One" which was what I was going for.  Add in the legendary Boss durability and lower than boutique prices and you have a very sollid Leslie sim IMO.  But you are totally right.....different tastes!

The Analogman Bi-Chorus can be set for a "normal" chorus on channel A and a pretty decent leslie sound on the "B" side.

I've long searched for a decent Leslie sim that's a good size. I have had the CLS222 and quite frankly, unless you're prepared to re-amp it properly so it runs at line level then it's far too noisy and adds too much drivey hiss (note my system is pure front end analogue). Re-amping the thing is also hard, as as far as I am aware you need 2 boxes not one to do this, although dan@ the gig rig is bringing out a gizmo to do this soon.

Also, for my money, unless you're running a stereo rig, a Leslie sim is pointless as you won;'t get the right 'sweep'.

Having tried most, I have to say the Korg G4 is the best by miles. DLS and HK are too too noisy, and the RT20 to me is more chorusy. The G4 is one heck of a piece of pedal board real estate though*

One thing that I sometimes use is the TC SCF on pitch mod. This is slightly Leslie ish.

*My pedalboard, for those that have seen it, is hollow and I place the 'set and play' boxes underneath the main pedal deck. I think I can squeeze the G4 into the cavity, and as I tend only to use it on one setting, this may be the way forward and then control it off my switching system.
