Feature:
Very,very simple and easy to operate.

Quality:
Very well made product.

Value:
Unbelievable value.

Sound:
You won't find a better sounding unit for under a thousand bucks. I know, I spent a month going through every effects unit in the store. Buying them and taking them back before my 30 days were up. When I got to this one my search was over. I also have a high end lexicon unit. When I don't want to fiddle around with a bunch of paramiters and just get the job done, the M300 is just what the doctor ordered.

Support:
Do not know. Never had to call.

Overall:
I have often thought about buying a second M300 just to have it. If one day they stop making them, I'll have a second one.

Feature:
There isn't as much control over the nuances of the sound that you would find in more expensive units, but the sounds are so good you won't miss the tweeks 95% of the time

Quality:
Looks gorgeous, feels solid.

Value:
Talk about "bang-for-the-buck" ! I was very impressed with the quality of this unit for the price.

Desirability:
Very attractive! Both in terms of sight and sound. I'm considering picking up another.

Sound:
Excellent sounding reverbs and delays. This unit lends itself more to studio/recording setting, or uses where you will not have to switch effect settings on the fly (like in the middle of a live song), since there is a little bit of a delay when switching settings. In a recording situation, this isn't a problem at all.

Support:
Haven't needed to deal with them, but it was very easy to find multiple ways to contact them if I ever needed to.

Overall:
This is a great sounding unit at a great price. I've been working with it pretty heavily for a couple weeks now, and have been very impressed.

Feature:
True dual engine. Really nice for low dough.

Quality:
Nice.

Value:
A steal.

Desirability:
Sexy as any.

Sound:
Nothin flashy, just useful.

Support:
Don't know.

Overall:
Great value, and not noisy.

I was waffling between the Lexicon MPX200 and this TC M300. I had the chance to try them both extensively on various setups in both analog and stereo routing.

They both sound fantastic. Very lush reverbs and no noise that I could hear. I had a guitarist friend of mine playing with the effects. He just about soiled his drawers over the super clean effects. Once he recouperated, I asked him if he would like some reverb added to his sound. "WHAT!?, the reverb isn't even on!?" Yes, this unit sounds that good.

One edge I would give to Lexicon is the independant compressor. With the M300, the compressor is an option of the effects engine, so if you're using the compressor, you can only use compressor+verb. One the MPX200, you can run effects+verb+compressor. Not a biggie for me personally, but it may be important to some.

This unit is proced closer to the MPX110. I believe this unit kills the MPX110 personally, in both functionality, features and sound quality. The 110 is no slouch, and sounds great, however I find the reverbs cleaner on the M300 than they are on the MPX110. The gating is tighter, and more easily defined with precision than on the MPX110.

Different, yet a similar value to the MPX200, and cheaper to boot.

Feature:
Nothing special, just good sound for the price.

Quality:
Built very well.

Value:
For the price it may be one of the richest verbs that there is.

Desirability:
Very sexy.

Sound:
Very rich verbs and a nice delay configuration.

Overall:
This one will be with me for sometime. Great for vocals, but a lot of the verbs can tend to sound a lot alike, but they are a very nice.
