You don't say what sort of music you want play. If just thumping some country/rock, this could well suit you. If you want to bow classical, not so much.
Thump along the edges to see if there are seam separations. Is the top deformed? Are there cracks - repaired or not - in the top/bottom? Has the neck been repaired? Is the neck straight? How does the fingerboard look? Do you like the FEEL of the neck (Kays tend towards the thin)?
If positive answers to all of the above, and the price is more under $1k than $999.99, this could be a fine bass. Setup, including strings, could easily run around $500.
But quite a few things in your rather brief post strongly point to you not being in love w/ this particular bass, which pretty strongly supports looking elsewhere. Last thing you want is to invest $1-1.5k into a big piece of furniture that you don't like or want, and then have to get rid of.
Like Greg says, if you spend another grand to get a Shen, you will end up with a more solid tool. And looks ARE important. Do you dig a beat up warhorse, or do you want something new and shiny?
Finally, any general idea of where you are at?
