Beseler Enlarger and Accessories, what to do with them?

Hello all,
I am new to this forum, please forgive me if this post is not ok.
I have an unused Beseler 23C11 enlarger with a stabilized power supply and dual dichro. Also a Radius ELD tungsten halogen lamp bulb and a set of Kodak filters. Was gifted these 20 years ago when I had hopes of setting up a dark room, unfortunealtey never had the proper space for doing so.
Do any of these items have any value? Shall I try to sell altogether with my other dark room supplies? Or individually? Over past 5 years I've posted the enlarger on Craig's list several times but no bites. Any suggestions would be appreciated.

There is just not a lot of demand for enlargers these days.
It’s not that someone isn’t looking for one it’s more about connecting with the right audience.

Look on eBay at completed listings and they are all over the place with some not selling at $50 and others selling for several hundred.
You could try self it on eBay or on this site in the classified section but you may have to be a member for a period before posting.
Other options are to find a school and donate it to them or give it away via Craigslist.

Good look.

You might try listing on Craigslist, in your local market so the issue of shipping cost does not rear its ugly head (like it can when you try to sell enlargers via eBay)...it is how I found the proud owner for my Beseler 45V-XL enlarger and lenses. He got a great deal, I got it off my hands. Listing on Craiglist does not automatically mean 'giving it away'

There is more demand in some areas than others. A Beseler 23cii is a premium medium format enlarger that sold well in the North American market. I’ve had slightly better luck with Offerup than CL. What’s the location?

Welcome to Photrio.
Around here, there seems to be a fairly lively trade on Craigslist.
Perhaps you would like to share a copy of how you have listed it in the past - we might be able to help you with suggestions.
One suggestion, of course, is to have the name correct - I've fixed the spelling of Beseler in your thread title .

Craigslist definitely. Look at sold listings on eBay to get some idea of prices. A 23C that is virtually new, with the original boxes for shipping should be easy to sell, given a bit of patience. New prices are not a good indicator of used values.
