now we're getting somewhere.
im getting the impression that, you are not into scratching, have capabilities for a digital input, but yer afraid to jump onto that boat for fear of losing quality by trusting the internal preamp on a digital vs an outboard preamp on a normal analog table.
my advice would be to get on the hunt, craigslist electronics section, flea markets, garage sales, find a table that looks nice (if it was taken care of, it might be for a reason), and then just snag any vintage preamp you can find, or a decent dj mixer. i dont think any dj mixer is going to have 'worse' preamps than any decent standalone, until we start talking spending real money. again, consider the market, maybe avoid any colorful 'look at me im a dj!!!' type mixers and stick with the professional - this will get you going and you will get some firsthand experience on what you like / dont like. again, 'best' is not really attainable here, only 'accuracy' - and since part of your process is going to be altering the source anyway, does accuracy really matter? (ie. if you get a dj mixer you can tweak the eq)
eventually you will talk to people, try out things, and learn what kind of things to look for - or i can just tell you that a 1200 and a vestax is a the way to go, but do i really need to?

unfortunately, i cannot comment too much on digital turntables as i only use one. to my ears, the digital out is nothing special, but it's flat, clean, and convenient. this works for me and might for you.

well by exceptions i meant, sometimes you can find something for cheap even though it's totally legit. example, i recently scored a great mixer that wasn't advertised well and looked jacked up - to most it looked like a mixer with a broken fader but ive fixed faders on tons of gear, so to me it looked like a good deal.
the other end of the exception list is the stuff that costs a lot but isn't really that special - it's not always bad gear, don't take it that way, but imo it's not worth the prices they pull. $1000 might get you flashy lights and a decent mixer, but $1000 might also get you a minimum-frills mixer with a ton of character and top-notch sound.
the used market is generally a good indicator of 'worth' as the stuff has been around the block and people don't have marketing teams. so you can use that to gauge what's 'good', then look for a deal when it pops up.
personally, i would avoid ebay, as you're likely to just get market value on something that might have been broken the day before it started working again and was put on ebay 'in full working order' (i only say this cause i know people who've done it).
get out in yer community and freak out the old timers.
finally if you really just want name dropping:
technics, ecler, vestax, thorens, dual, allen+heath - by no means exclusive and not all inclusive
