By turnkey I'm assuming ready to cut including the plasma cutter? Torchmate sells a model 4400 with a lincoln cutter that will run about 20k. They say ready to cut in 30 minutes. Baileigh Industrial has a number of tables in that size range for 15k and under. I think I'd suggest doing some searching on this site as others have asked the same question and there are a number of options considering your budget. Hypertherms are great cutters. I've have a couple for use on plasma tables and they have been very dependable and cut well. The new 45xp and 65 are very good machines. Many companies that make plasma table setups seem to come and go. Decide if you want downdraft or a water table and what the max thickness metal you'll be cutting. If you don't already know the basics of CNC and the software, what software and training/learning will be an important aspect of your purchase. Don't get something that you'll regret or need to upgrade. Find a couple companies with good after purchase support that have good reviews and make some phone calls and see who "clicks" with your needs. You should have no problem getting what you need for the budget you mention. If I was spending that much money, it would be worth a trip if necessary to see the machine in person, watch one operate and discuss options with them.
