This one is nice. I like it a more than the Clavi in in Scarbee Vintage Keys. YMMV of course. Currently on introductory offer for $26.50.
 
And great customer service, I had an issue with the downloads and received a very prompt response to my email and a solution from Per at SampleTekk.

I've used Sampletekk quite a lot in the past and always found Per very helpful indeed - a company I like dealing with. Must go and check out the demo
