I was only kidding. I ain't got pots o' coah either, so I'll join in!
What about the Tyrone Davis stuff, you can get 'em all for under £20, and the ones I know are quite good...
Mellow Fellows - My baby needs me - Dot - OK... I know this is a bit more than £30, but you can pick a minter up for £50/60.
Voicebox - I want it back (your love) - A fave of mine, and only a twenty-five-quidder!
Nina Simone - Be's that way sometimes - RCA - Easy pickup for £20, demos bit rearer though, maybe about £35
Don Gardner - Somebody's gonna get hurt/Ain't gonna let you put me down - Tru-Glo-Town - A mere £30 touch (if that!), and two fantastic sides! The first's a big beater (that sounds shit rare if I may add), and the other's an up-temp R&B stomper dancer thingy
Don Gardner - There's nothing I want to do unless it's with you - TNT - Another big beater that I was lucky enough to pick up for $10 (evilbay), £20 off manship. Unfortunately with this one the B-side's shite - bit like Cavaliers on Shrine with lots of screaming and shouting in background.
Paul Sindab - Since I Met You/I'm Up Tight - Hype - A-side's very slow and sensual, a perfect ender, while flip is an up-temp dancer. Got mine from manship's carboot for £15 I think (warped), would be £30 mint, and while we're (I'm) on the subject of Paul Sindab, if you see 'Can't wait no longer' on Kasika listed for less than £100 - buy it - it's AWESOME! Appears on eBay now and again, make about $150. Trust me. Buy it even if you don't know it. It's good. Very very good. Nuff said on the matter...next;
Maurice Long - I don't love you anymore - A whole bunch of WOW's for £20, what more can you ask for?!
Harold melvin - Prayin' - Source - Can pick it up anywhere for about £15, although I was lucky enough to get the 7mins 30secs long 12" cut, which is a lot rarer (and better cos it's longer), which is worth about £100. One of the best 70s/80s dancers ever IMO.
And I'm sure there are many many more...just can't be arsed to list them all
But it's true what you said about the Eddie Billups (Ask My Heart) thing, quality seems to speak (or sing) for it's self, the high price/rarity just makes it more desirable.
How about while we're here (and I'm not trying to steal your limelight Trouty), also listing the records that cost a fortune but are utterly dreadful... I'll start (most of mine can be heard on Manship's Rarest Of the rare):
Primers - How does it grab you - Hale
Can't think of any more just yet. Will add some later after trawling ROTR
