Jerome,
In my experience
Literary Review are fast payers,
and you get a complimentary magazine,
The Speccie people sometimes take ages to cough up, but
The Oldie aren't too bad as a rule.
I think they all work (loosely) on the notion of settling up one month in arrears, so you and Bill ought to be getting your payments any time now, I should think.
On odd occasions I've waited so long that I've forgotten I was even due to get any money - then it's a lovely surprise when a cheque pops through the letterbox!
(Realistically though, 25 quid isn't ever going to change my life! I just like to win

)
