Bought the PM70 from them recently when looking for some CP70/80 sounds.

$19.99 for limited time.
 
For the price I think this is quite a good set if sounds will lots to play with.
 
They also have some interesting sample collections and the pricing is reasonable.

Only thing you need to be careful of is that they have dropped (temporarily I hope) doing the sample packs in Kontakt format - they now only offer packs (just new stuff I think/hope - but check) in Ableton Live and EXS format.
You can load EXS into Kontakt but it's a bit of a pain.
