Help with some Vintage gear???


So I have some vintage classic pieces and was wondering what they might be worth and where would be the best place to post them. All of the items are basically BRAND NEW and have never been used, mounted or connected. So while they are old (New Old Stock?), they are virtually brand new:

Grace 747 Gyro Master Tonearm with original box and all parts. It has been taken out of the box to be just sit atop a turntable for the sake of taking pictures.

AudioQuest Leopard ToneArm cable- brand new.

Ortofon MC2000 (NOT the MKII). This is the original classic audiophile moving coil in its original presentation box with all accessories, graphs, tools, etc. Never mounted.

Ortofon T-2000 matching step up transformer for the MC2000.

All were purchased by myself new. Any thoughts on what I might list them for and where?  Or... should I keep them and set them up on my Clear Audio table?

Thanks in advance...

@sherf : Sorry for misreading your post! Yes, the 747 is worth more than the 707. About $400 + !
It took ages for me to find my ortofon MC2000 in NOS condition @lewm  
I've seen some bad samples
Ortofon MC-2000 in original box cost over $1.5k in perfect condition.
People who quotes $400-500 pirce have no idea about the prices, this is the price for a dirty worn cartridghe without box, docs etc. If you have full set in perfect consition this is VERY RARE and expensive! Do you have this box, docs, tools, weight, headshell ? Dedicated SUT cost about the same, definitely over $1k.

I didn’t mean to be a clod.  I have been searching for an OEM MC2000 and the SUT that goes with it, for a long time.  If you would list them for sale somewhere, preferably here on Audiogon, I would be a buyer.  I was hoping for a heads up, although I also realize that your mentioning the sale items here is yet another kind of faux pas.
If I decide to sell them, they will be listed on the normal boards.  The arm by the way is a 747 not the 707.  I was thinking the arm should be worth around $450 - $500 and the cart and SUT right at a $1000 for both?  
I’d be interested in some of your Ortofon stuff. Please feel free to contact me privately.
$200 - $300 for the Grace 707 arm (I have two). $400 - $500 for the Ortofon MC2000. I'd keep both (and the tonearm cable) and use them on the Clear audio TT. Along with the Ortofon SUT! You will have truly excellent sound from your favorite LPs!
