Hello and HELP

,
I have been on the acoustic forum because I saw a Henry Miller 4’ 7” baby grand at Costco Road Show with the QRS serenade system (for $9000) and thought… hey, I might want to take up piano and this one seems kinda cool... and even if I don’t “really” ever play I can listen to the likes of George Gershwin do his thing (making this a very expensive CD). Well, someone posted a link for a Casio PX-300 for $600 bucks… a far cry from the HM I was looking at and the subsequent search for a good starting level piano that will give me the most bang-for-the-buck (everything from Young Chang to August Forster to Estonia). Please do not think me a snob as an acoustic was my first choice… I never even considered a digital and do not even know how a digital varies from a keyboard (if at all). Could you guys/gals suggest a good starting digital/keyboard that has the closest feel, action and sound of an acoustic piano?? Since I do not even know if this is something I will want to pursue long-term, this just might be the best investment.
I would like to spend less than $1500
Thanks!!!!
