I've had nothing but the best experiences with TMR.
They've always communicated well, nicely over-packaged components and proven to be consistently accurate in their assessment and description of used gear.
Any company staffed by human beings can have something fall through the cracks, temporarily. That's what the telephone and email are for.
Hate to see a good company get thrashed on social media for a week-long delay. The little acknowledgement of resolution, dozens of replies down the page does little to fix the bad impression caused by the original post. At least it brought out many positive testimonials attributed to TMR. 

I like TMR because they have great descriptions of the condition of their items, along with detailed pictures. I purchased an int. amp from them once, which went perfectly.

As a person wanting to sell an amplifier to them, way not impressed. 

Although I have never purchased anything from TMR, I have had a couple of pleasant and responsive email exchanges.  These guys seem to be very legitimate.  They have a lot of great used gear for sale, at pretty attractive prices.  Because they tend to sell on the value side of the equation I understand that some of their purchase or trade-in offers may seem a bit low to some.  But you can't have it both ways: buying high and selling low isn't a successful business model.

If you are selling or trading gear to a dealer you only know 1 out of 4 things necessary for the dealer to make you an offer: the price you want for the gear.  The other factors are what the gear is actually worth (to the dealer's target market) and how much the dealer needs or wants to make on the transaction.  You may think you know your gear's worth but you probably don't.  And the transaction profit and back end costs are completely unknown to you.  At the end of the day your choices are to accept the offer, attempt to negotiate a better deal or just walk away.

I personally hate their pictures. While being in high quality and very detailed they never adjust the light temperature of their camera and everything looks "cold." Also, some of the prices are a tad too high in my opinion.
Just my 2 cents.
