Depends on how much do you like to spend.
For 600$ you can get a mint Theta Data II which is a great transport for the money. CEC5100 is also good, but not any better than Data Basic II, and much more expensive on a secon hand market.
For 2000$ you can get either CEC TL-1 or ML37. Both are excelent, but have different sonic virtues. CEC is more relaxed, ML has beter bass definition.
