KThomas,
I'm not sure what your budget is, but a safe option would be a Rega P3 (new or used)with a Rega cartridge. Rega carts feature a 3 hole mounting system which makes alignment foolproof. Other than setting antiskate, there's no other adjustments to make. It's about a close to plug and play as you're going to get, and this setup will give you a pretty good taste of what quality vinyl playback is like. Could you get better sound for less money? Sure. Could you get better sound for less money and no tweaking, adjusting, modifying, futzing? Probably not.
