Thanks guys, for your kind and considered replies so far
Michael K - Screwed Deck looks very nice indeed - just the kind of thing I would consider myself, had the review not passed me by; onto the list it goes!
Simon Die-Cipher - Hmm...at first glance, I wasn't entirely sure how I felt about this one. On one hand, I don't already have any dice-related effects, and on the other, I'm not much of a gambling routine type chappie.
However, the following comment of yours, from the review, seriously turned my head:

Then ask.
Did you choose the number 1?
Did you choose the number 2?
Did you choose the number 3?
Did you choose the number 4?
Did you choose the number 5?
Did you choose the number 6?
Amazing take on the effect - you make me hang my head in shame at my lack of foresight: Onto the list this baby goes
Part-Timer - Where abouts did you buy your version from? Whilst this may seem, potentially, to shout "dodgy dice" more loudly than the 'real dice' version, it's always nice to have an option!
Greedo - Many thanks for your sage advice; it's nice to have my quest to buy whatever comes out as the most highly-recommended tempered by some words of restraint
Of the kit I've bought over the past five or six weeks, I've divided it into three categories:
Absolute Knock-outs (Ie Strange Travellers, Kioku, Outlaw Wallet)
Reliable Workhorses (Ie Relic, Scorpion, Ladybug, Quantum Leap, Superfly)
So-so, Meh! (Ie Homicide Triology, M5, Mercuring, Nailed)
Whilst I'm in no way saying that the last category consists of duff effects, these are the ones that simply don't suit me personally, and which I cannot see myself effectively performing, persona-wise, so these are all being sold/recycled
From a presentational point-of-view, I do pretty much devote all of my spare time to the routining and practise of the former two categories, so I have no real qualms that I'm neglecting the core of my work in favour of the next purchase
Chris - Absolute magic - A good, solid suggestion (a book - at last!!

). However...sadly this doesn't meet with my Number 4 Criteria - if it
was readily-available, I'm almost certain I'd have it by now
So, sadly, I can't really add this to my list

On the up-side, that means you get to make an alternative suggestion!
Lindz - Cold reading - Hoorah! - another book (they're like busses, aren't they?!

), and this one DOES qualify. Whilst I only do a smattering of CR so far (mainly in conjection with Kioku or Reflections), I'd love to use more - onto the list goes this cheecky little puppy!
Dat - Far Sight - Funnily enough, I bought Bang-On yesterday
Far Sight looks interesting, though seems kinda' like it's main presentational vibe is designed primarily to be a magician-fooler (though I'm sure it plays strongly to a general lay-audience too!)
Oddly, I couldn't - for the life of me - find this item on Danata's website (Does that site even have a search function? All I seem to be able to do is select a category, and then have to scroll through miles of effects

)
Assuming this is in-stock...onto the list it goes!
THE LIST, AS IT STANDS SO FAR:
Screwed deck
Die-Cipher
Full Facts of Cold Reading
Far Sight
Once again, thanks for everyone's suggestions so far - keep 'em coming, as my quest continues
