My advice would be save a bit of more money and buy a reliable table, this would save you a lot of trouble in the long run and money too. You can also try to build your own to your specs but that takes a bit more time and patience. My local welding supply store has a Plasmacam that runs very good with rarely any problems which has made me want to buy one. Cheap prices look very good at first but it may turn into trouble later on. From my personal experience I will NOT recommend Lightning CNC tables, it has not been good from the start and I am almost double the money of what I paid for it getting it to work and no tech support after I bought the table. Just keep searching around and don't rush into buying.
This is my advice and good luck.
