Thanks for the replies, though I'm a writer for them, not the publisher.
Headstuff have published two of my books, 'Brainworks - Meditation & Mind-Hacks For Creatives' and 'Cannabis & Meditation - An Explorer's Guide', with 3 more books from other writers on the way. They're not vanity publishers, or POD, but pay me a royalty on each copy sold. I didn't get an advance fee, but for one reason and another I was fine with that. I'd have to speak to them before discussing actual figures with anyone, but it's a better rate than I've found anywhere else, though I admit I'm no expert, it was the first decent deal I'd been offered so took it.
I feel they're actually doing things for me that I couldn't do as well for myself, like PR materials on tap, book covers, wallpapers - that I have input into, which means a lot to me - anything I or they can come up with. It's not an endless budget by any means, but sales are good. I'm happy, I've got to say, I'd lost hope of ever seeing C+M in print. And yes, I preferred the old title too
Luckily no co-investment was required, I haven't put a bean into this, though I am required to help out as much as possible in terms of getting my work seen, which is fair.
If you think you've got something that might appeal they're worth a shot. I know there's a new forum underway, and a deal coming up for new writers so everyone gets their own pages,etc. Worth a look.
