@Goodman - thanks.
My story is this. I bought my 3rd real machine (NEOS 1000, NEOS 1500), a Babolat Sensor a few years ago. I paid $2200 for it. I had been refurbished including the tension head. The Sensor Dual new was $6000. I have been completely happy with my purchase. The machine is fantastic and does everything really well. I am happiest with the clamps and overall build of the machine.
All of that said, in retrospect, knowing what I know now, I might have sprung an extra grand for the Babolat or the Ghost II (and the comfort of a new machine and a warranty). Why? Well as nice as the Mighty Sensor is, it doesn't have all the bells and whistles of the newer machines. The Ghost II has an automatic magnetic table lock, nicer key pad and display etc. I know Babolats have a strong following among tour stringers, but these other machines are really nice. They have more features, are more ergonomic and are more portable (by and large).
@Kdude you can't go wrong with a well kept used Babolat. But you should weigh the price you pay for that versus something like the Wilson Baiardo L or Alpha Ghost II. Look at the features included versus the Star 5. At that price, you're going to get a machine that is far and away more than you need; and that is not a bad thing! But don't jump on a Babolat simply because you read lots about it on these boards. There are newer machines
available new at about the same price with more and slicker features (it's called progress).
In summary, think about a stringing machine like a PC. Would you pay top dollar for a 5 - 7 year old PC? Heck no you wouldn't (if you have a brain in your head). Electronic stringing machines are very much like PCs. They both have motherboards, memory, and electronics. Think about how much the electronics in a PC mother board have advanced.....in college, one of my professors (teaching me BAL teehee) said "One day, one day we will have a gigabyte of disk. Just think about that. It will take a whole building to house that much disk." 37 years later, I have 64 GB on my dadgum phone! BTW - my senior year in college, IBM release the first PC. I came standard with 2 - 8 inch floppy drives. One for the operating system and the other for your programs and data.
