Considering selling my restored Garrard 301

If the 301 wasn't "restored" by a recognized vendor, you may only get the usual unrestored pricing. 

Your table/tonearm combination is pretty nice.  Assuming that you properly restored the table, it would be hard to beat with any modern alternative at the price you can expect to get for it.  There are a lot of listeners who prefer the 301, or 401, or Thorens TD 124 over almost anything else.  A local dealer in my area reconditions these tables and recommends then for use in systems well north of six figures.  Good tonearms are getting hard to find and your SAEC are is also hard to replace with anything near its going used price.

What do you want from a modern table that you don’t think you are getting from your 301?  That answer might help someone in suggesting alternatives.

I have in the past been very loyal to the ID Motor TT's.

Nearly 20 Years with a Garrard 401- Martin Bastin Overhauled - 9 Stone in Weight Granite Plinth, which was swapped out for a PTP Solid Nine with PTP Bearing.

I see from your post there is not a dedicated Platter Bearing Upgrade or Speed Controller referred to.

I am an advocate of the dedicated Platter Bearing Upgrades and the use of the SC.

I still own the PTP Solid Nine, but have today found the DD TT's that are overhauled with a modern design concepts for the Speed Control and Platter Bearing much more attractive to my tastes.

As for a valuation of your own TT, the SAEC has a value of approx' $550 if a price is chosen to rouse immediate interest.

The Cadenza Blue will be a difficult sale, if too much is wanted, Trade In Value and a few 100 Hours of usage life should rouse a interest?

The Beauty of the Plinth and the Value of the Plinth is in the eye of the Beholder, think maybe in the area of $150, as a means to saving a DIY Project for somebody wanting to experience this Plinth Type.

The 301 will be best assessed if looking at the Link and the Historical Sales available to be seen as well. 

If it is off any interest, there are Idler Drive TT owners who own in conjunction Vintage DD TT's. Maybe this might help with your making a decision on where to look into for the next TT.    

Yes. List the combo with clear, in focus photos. But you'll get what the market will bear.  Curious what the "comparable alternative" would be.

Would there be people interested in buying it at a price that would enable me to purchase a comparable alternative or a trade.

Jim Cambell did the restore for me as I live east coast- the deck was original owner and other than a single dust bunny, it is chip and scratch free (no paint needed. I had Jim do a top to bottom restore. The arm came in the original box. I bought it from someone whom I know well and has more turntable knowledge than most I have met. 

The arm/cart combo is a flavor I like and I have spent years learning how to set up tables correctly.

I'm simply not a woodworker and my plinth lacks the correctness required to make a 301 sing. It's big and heavy but that does not make it right. 

I really am being a bit foolish thinking of selling it, I love the pace and would think only a good DD what have the same ability.

Maybe I just need to have a pro build the plinth.
