Forum member by the name of Tom has underquilts for sale on page 3, listing is titled 'Huge lot of equipment'. I have bought from him and he is amazingly helpful, great to deal with. I had an awesome experience with him and have been eyeing the 3/4 one myself but currently on the fence.
I've found the information regarding a subscription but considering I have nothing to sell, I'll hold off on that for now. But out of interest does that give one instant messaging or does one still need to waffle on abit?
