The Alesis QS8.2 leaps to mind,as I think it's a fantastic starter keyboard & very nice quality for the price-which makes it an exceptional value.
It has something like 640 sound presets with 48kHz sound quality(better than cd quality),a nice assortment of 24 bit digital effects,very decent quality acoustic programs & synth sounds with some sound shaping capabilities.
It is a 88 key,weighted keyboard and it goes for $699 at Sweetwater.com -which is the lowest price I have found for this board.
It's original retail value was $1499 and the price came down considerably,due to it having been released in 2001,& also because the release of the Fusion brought the down price also.
The only real drawback to this keyboard,is that it comes from the factory with just 16MB of sound samples-which is considerably low in comparison to other keyboards for under a grand that typically have anywhere from 25,to 64MB of ROM samples-of which is also a contributing factor to it's very cheap price currently.
However though,you get what you pay for & at it's current price,I think it's a pretty fair deal and I just may grab one for myself.
