Two weeks ago i got another album that an 808 fan would be insane to miss out on-Gargantuan by Spooky. On an Orbital tip, but as consistent as any of their albums (which is saying something).
I read about it a while ago on this forum, and seeing it in FOPP in Camden (they also had Analogue Bubblebath III-dunno how that ended up there!)risked it. It was a risk worth taking!!!!
Also on the same slant as Autechre-'Soup' by Bola is a good album. Also if you like 'Incunabula' you should check out the other Artificial Intelligence albums:
Artificial Intelligence I
Artificial Intelligence II (both various artists)
Surfing On Sine Waves-Aphex Twin
Bytes-Black Dog Productions
I don't think that's all of them but they're especially worth checking out. Also are: B12 Electro-Soma (I don't have this but desperately want it), most by Plaid ('Trainer' has all of the tracks from the incredible 'Mbuki Mvuki', btw) or anything by the Black Dog. 'The Book Of Dogma', a collection of their early stuff, looks awesome and is out in a couple of weeks (or less??)
I dunno if you'll be able to buy that lot with the money from the Squarepusher CDs but they are all worth a look!
