It looks like the suggestion for an electronic machine was an obvious jest to the OP due to his inability to narrow down the playing field. But he took it seriously by asking for more electronic machine suggestions (again showing he does not really know what he wants), so now people are trying to talk him out of that jest.
I'm fairly certain it was a serious suggestion; one of the common pieces of advice on here is 'as much machine as you can afford', and when someone states they're willing to pay up to 10k then they can afford pretty much any machine.
I think most of us are relatively conservative when buying the first machine, largely because we haven't strung before. There's that slight unknown, and for me it was finding that level not so much as to what I could afford, but that I would be comfortable paying in the event that I hated it. After a reading a lot of threads (starting with what was a fairly new sticky at the time ;-)), I decided to buy a crank.
For some hobbyists, the first machine they buy will last a lifetime. For others - myself included - the longer we do it, the more likely we are to upgrade. After about 18 months I added a Wise to my machine, and when I next move house I'm intending to have a stringing/hobby room, at which point there's a high chance I'll upgrade to one of those 'low end' premium machines. It's not because I need it, but because I'm passionate about it. I think I'm the sort of person jim e has in mind when he advises an electronic machine, because if I'm going to end up with it eventually, then if I can afford it, I may as well have it from the start!
For our OP, I'm not sure what the best advice is. He had his Klippermate for one weekend before declaring he was going to upgrade, which suggests to me that he found the going tough and is looking for a magic fix. He keeps coming back to speed, without really realising that the biggest gains in this department can only come from practice. Judging by the volume he posts, he's clearly passionate about tennis, so the interest may last... or it may be replaced with something else. We've all been 15, and those of us who can remember what it was like will probably agree that when you really liked something it was absolutely the best thing in the world ever and you obsessed with it... but all of a sudden something even better could come along and your attention switched. That's not a criticism: those sort of heightened emotions were the some of the best part of being a teenager, and I quite often listen to music I liked around that time because it can remind me what that feels like. The crappy parts of being a teenager are obviously best forgotten.
My general feeling at this stage: hold onto the Klippermate this year, get used to it, and see where you are this time next year. If you're only using it once a month, you may decide you've got all the machine you need. If another interest comes along, you may decide you've got more machine than you need. If your tennis is improving, you're going through strings quickly, you have teammates who would like you to string for them, that may be a time to upgrade.
Things do get clearer as you get older, but it's largely because you have less time to think about things and so have to get used to making snap decisions.
