Where do you consider to be the best place for module selling? My local gumtree rarely has any interest for it.

Basically, I was looking to give someone UK side a great deal on a marbles clone and a lyra 8 fx.

I'm super broke at the moment, as I just quit my job in mental health because of my GFs suicide at the end of last year, and the NHS spend ages getting a reference out so I'm in limbo for my new job, and need a fast sale. Ugh.

Anyway, could one of you lovely people point me in the direction of somewhere reliable that isn't ebay that you all use? I would love to know where you think the best place to post them is, for UK only. Thanks in advance!
